Introduce a two-layer domain system (ground/air) that separates units into
independent simulation layers. Air units ignore the nav grid, never collide
with ground units, and can only be targeted by weapons listing "air" in their
targets. Hover units gain water-crossing ability via the move class cost table.
New content:
- Fighter (air interceptor with AA cannons)
- Bomber (ground-attack aircraft with bomb rack)
- Hover Constructor (water-crossing builder)
- Airfield (produces all three air units)
AI gains air superiority management: interceptors hunt enemy aircraft instead
of joining ground pushes, and the production mix auto-counters observed enemy
air. Ground anti-air (rocket troopers/tanks) also gain targeting weight.
Rendering adds a dedicated depth band for aircraft above all ground actors,
plus a displaced shadow sprite for altitude perception. HUD tooltips display
domain and weapon targeting information.
Validation ensures domain/moveClass agreement, requires at least one anti-air
weapon when air units exist, and excludes air classes from corridor generation.
Comprehensive test fixtures cover domain separation, collision, splash, and
order handling.
feat(zuma): redesign level 7
feat(shift): add 9 new artwork pieces
chore: remove Worms game entirely
- Goo Tower: introduce `asleep` state for pile balls. Asleep balls ignore physics/wandering and cannot be picked up until they gain a clear line of sight to an attached structure. Adds zZzZz visual, editor toggle, auto-play filtering, and logic tests.
- Goo Tower Lvl 9 & Zuma Lvl 7: completely redesigned terrain, ball/pile positions, and pipe placement.
- Shift: register 9 new artwork pieces.
- Worms: remove all source files, assets, verifier, build docs, and game wiring.
Add Worms (inspired by Worms Armageddon) as a new arcade game with:
- **Procedural terrain** — seeded Island and Cavern generation, full destruction via `carveCircle`, girder placement, ROCK immunity
- **Bespoke physics** — worm locomotion (walk, jump, backflip, ballistic flight, fall damage), projectile simulation with wind/bounce/homing, ninja rope with corner wrapping, explosion geometry with linear falloff
- **16 weapons** — Bazooka, Grenade, Cluster, Shotgun, Uzi, Fire Punch, Dynamite, Mine, Air Strike, Homing Missile, Holy Hand Grenade, Blowtorch, Girder, Teleport, Ninja Rope, Skip Go (+ Surrender)
- **Match rules engine** — 45s turns, retreat phase, sudden death with rising water, crates, mines, oil drums, chain reactions, deterministic hash-based state
- **8 themes** — Forest, Desert, Farm, Hell, Arctic, Jungle, Construction, Space with full procedural palettes and drop-in art hooks (`data/worms-artwork.json`)
- **Phaser scene** — mode select, quick match setup, camera, HUD, weapon panel, slingshot aim, 2-player hotseat
- **Headless verifier** (`tools/verifyWorms.js`) — 207 checks across terrain, physics, weapons, and match logic; deterministic through the sim
- **Wiring** — registry (iconFrame 92), main.js scene registration, slug dispatch, asset manifest resolver, preload
Also updates `level-008.json` with new solid/spike geometry, additional balls and strands, and repositioned pipe.
Remove the entire Angry Birds implementation including physics solver,
game logic, Phaser scene, level data, verification tool, and registry
wiring. Also delete the build-plan documentation.
Meanwhile, upgrade Goo Tower rendering: spikes now have faceted steel
teeth with dynamic lighting, rust speckling, and twinkling glints;
lava features layered heat gradients, animated flow streaks, and
rising bubbles. Update gootower levels 6-7 and zuma level 6.
Replace the "ride the rim" gear mechanic with instant ball destruction on
contact. Update hazardAt(), resolveTerrain(), and all related tests.
Redesign level 5 ("Watch Out") and level 6 with new terrain layouts
featuring gear hazards, updated ball/pipe/pile positions.
feat(shift): paginate artwork selection and reveal on completion
Add page navigation to artwork cards when there are more than one page,
and fade in the completed artwork over the puzzle after winning.
chore: add 9 new Shift artwork entries
AngryBirdsLogic.js layers the game onto the Wave 0 solver: wood/stone/ice
plus TNT with distinct density, friction and fragility; damage as a health
model with crack stages rather than instant shattering; all 8 birds with
one ability per shot; scoring, stars, win/lose, and a stepSim -> events[]
contract the scene replays as FX.
The load-bearing discovery is that damage must read approach velocity, not
the solver's accumulated normal impulse. The accumulated value carries the
static load of everything stacked above: measured 3.4e5 at the base of a
10-block stone tower, above the threshold that should shatter wood. Wiring
damage to it makes tall towers quietly crush themselves at rest, and it
reads as a level-design bug rather than a physics one. prestep now also
publishes contact.impactImpulse — the momentum needed to stop the approach,
zero at rest by construction. Resting fell to 2.4e4 against real hits of
1.9e5 to 2.7e6, and the whole material table was calibrated by measurement.
AngryBirdsGame.js maps the 2400x1080 logical level through fixed sx()/sy()
helpers at scale 0.78 rather than zooming the camera, which keeps HUD text
in plain screen coordinates. Slingshot drag, ghost trails of previous
shots, level select, star tracking and progress persistence are in. A
follow-camera is deliberately deferred to Wave 5 — it is pure presentation
and cannot be validated headlessly.
Six starter levels ship as the Poached Eggs opening. All stand unaided,
none damage themselves on load, and a greedy aim sweep clears every one.
Registered as slug angrybirds, iconFrame 92, under Video Games.
tools/verifyAngryBirds.js -> 114 checks green. Peggle (909) and Excitebike
(620) still pass; Goo Tower's 2 failures are pre-existing and unrelated.

Angry Birds is fundamentally a rotating rigid-body stacking game, and
neither existing engine could be extended into it: PeggleLogic collides a
moving circle against static pegs with no rotation, and GooTowerLogic has
no angular state at all because its rigidity is emergent from
triangulation. Matter.js ships in the CDN Phaser build but is not
importable in bare Node and not reproducible, which would forfeit the
verifier, the generator's measured star thresholds, and the editor's
winnability gate.
AngryBirdsPhysics.js is a bespoke solver: convex polygons and circles,
uniform-grid broadphase, SAT with reference-face clipping to 2-point
manifolds, sequential impulses with warm starting keyed on stable feature
ids, Coulomb friction, split-impulse position correction, and island
sleeping.
Split impulse rather than plain Baumgarte is the load-bearing choice.
Biasing the real velocity makes penetration proportional to load, so the
bottom contact of a 10-box tower sank ~9x deeper than the top and the
stack sagged 12.85px. Correcting position through a discarded
pseudo-velocity removes a fixed fraction of the excess per substep
regardless of load; sag is now 0.46px per contact, exactly the slop band
we deliberately allow.
Gate: 10-box tower settles in 0.68s and sleeps with <1px drift and 0.35
degrees of tilt; friction holds on a 15 degree slope and slips on 40;
replay is bit-identical and frame-rate independent; 40 monkey seeds
produce no NaN, no overspeed and no sinking.
tools/verifyAngryBirds.js -> 51 checks green.

Playtest fixes (two reports, both bugs):
- Bad ground no longer instantly crashes: holes and obstacles only
put you down above surfaceCrashSpeed; below that you bog to a crawl
that is capped under the crash speed, always escapable
- Steep ramps (45°) no longer crash: launch lifts the bike clear of
the lip, pitch is clamped to pitchMax, and landing angle is clamped
to landGroundAngleMax so straddled cliff edges don't count as
rideable surfaces
- Harness now drives every ramp at seven speeds; no crashes allowed
Wave 5 polish:
- Scenery: infield and apron shrub rows (bush, apronBush, tuft)
transcribed from NES track maps
- Ramps given readable silhouette (packed-earth hatch, dark stroke,
lit crest, sheer-face cut)
- Gaps show infield through lane; lane dividers and cool-zone
chevrons fixed for alternating-lane contrast
- Snow and night themes retinted for visibility
- iconFrame 91 already painted
Tooling:
- Map reader masks ramp columns to avoid false mud/cool-zone detection
- All 10 track qualifyMs retuned from playtest measurements
Updated build plan and sprites docs.
Address three fidelity issues found during Brian's playtest:
- Throttle: base speed 150→175, heat now chases a target (0.5 for A, 1.0 for B)
so holding A alone settles the meter halfway without stalling.
- Turbo: overheat window extended to 6–8 seconds (heatRiseRate 1/7s), turbo speed
275→235 against 175 base (57% boost). AI rivals now use hysteresis (heatOff/
heatOn) instead of feathering around a single threshold.
- Landing: tolerance is lopsided — rear-wheel-first is safe (landCleanBack 0.45 /
landHardBack 1.20), nose-down is strict (landCleanNose 0.32 / landHardNose 0.92).
Crash rates across banks dropped from 1.3–5.9 to 0.2–3.0 per 1000px.
Other changes:
- Qualify targets: max(human × 1.06, expert × 1.12) so a perfect ride has margin.
- Fix NaN in countdown caused by renamed heatRate constant.
- Soak bands re-based; added monotonic ordering check (expert > human > steady > naive).
- Title screen now shows controls and "LAND REAR WHEEL FIRST" hint.
- All 10 track qualifyMs values retuned to new physics.
- Generate 60 levels across 5 themed tiers (Downtown, Freight Yard, Airport Apron,
Construction, Night City) with guaranteed minimal and unsolved board states
- Rewrite generator (tools/genRushHour.js) with refine() pipeline that strips
redundant vehicles and re-hardens boards, plus hill-climbing phase B
- Add comprehensive verifier (tools/verifyRushHour.js) checking solver correctness,
structural criteria, MINIMAL/UNSOLVED properties, and curriculum shape
- Implement procedural vehicle art (RushHourArt.js) with baked textures, per-theme
decals (hazard, hivis, freight, neon), and themed board surfaces
- Move level bank to assets/gamedata/rushhour/levels.json and fetch on entry
instead of preloading at boot
- Restructure level JSON with tiers, level names, par, and difficulty metrics
(decoyDensity, targetRetreats, firstMoveFanout, carsMoved)
- Update level select to display tiers with themed swatches and color-coded labels
- Show level name and theme in HUD during gameplay
- Tighten hint solver with maxStates budget to prevent main-thread stalls
- Update PreloadScene to remove rushhour.json from boot-time assets
- Reduce pushSpeed across all 20 levels to ~60% of original values in
tools/genZuma.js, making the chain advance more slowly and giving the
player more reaction time. starScores() thresholds auto-adjust downward
since they are derived from pushSpeed.
- Add per-level background art (zuma-background-1 / -2) alternated per
level via a new `background` field in each level definition; draw it in
ZumaGame.drawBackground() over the solid fallback rectangle.
- Register the two new background textures and sfx-zuma-lose in the asset
manifest.
- Add playLoseFanfare() mirroring playStartFanfare() to duck/pause music
and play the lose SFX when the chain goes over the edge (onLost).
- Add a black stroke to the "ZUMA!" win banner for readability.
- Bump music volume to 0.5 in zuma-music.json.
Introduce underground tunnel sections to Zuma levels, letting the
chain roll out of sight and back in. Tunnels are arc-length intervals
on the path; while a ball is submerged it is inert — ignored by shots,
the laser sight, and explosions — and the path itself is drawn as a
faint buried trace beneath any live section that crosses it.
Engine (ZumaLogic.js): TUNNEL constants, normalizeTunnels, isHidden,
visibilityAt, pathSpans, sampleRange, nearestS; createLevel,
syncPositions, applyPower, stepFlights, and rayHit all honour
submersion. validateLevel lints mouth placement, spacing, and the
40% max-hidden fraction.
Game (ZumaGame.js): depth layer reorg so a live path always wins an
overlap with a tunnel stone; addPortal draws the two-layer maw (stone
below the chain, mouth above it); drawPit replaces the old skull with
a broken-stone collar and vapour swirl; startPitFall rolls the lost
chain over the lip in order, shrinking marbles into the dark; the
level-start fanfare ducks the soundtrack via MusicPlayer pause/resume.
Editor (ZumaEditor.js): new Tunnels tool with click-to-place,
drag-to-slide, right-click-to-remove, ESC-to-cancel; three graphics
layers (buried path, live path, handles) matching the game's
stacking; queueGameAssets so editor Test Play has the lazy art ready.
Art: ZumaPortal.js (carved serpent-head maw, symmetric so one
texture serves both ends) and ZumaPit.js (shaft of darkening discs
read as depth, not a painted circle).
Audio: four Zuma SFX (shoot, hit, start, explode) and a three-track
soundtrack wired through data/zuma-music.json and the asset manifest;
genZuma.js gains a tunnels column (fractions of path length) and
verifyZuma.js gains a tunnel test suite.
Significantly raise pushSpeed values across all levels (roughly 4x increase)
to make the game more challenging. Updated corresponding star score thresholds
proportionally. Adjusted editor UI max pushSpeed to 400 and updated validation
constraints to match.
Changes affect:
- data/zuma.json: level definitions with new pushSpeed and starScores
- src/games/zuma/ZumaEditor.js: editor input max value
- src/games/zuma/ZumaLogic.js: validation range
- tools/genZuma.js: generator table values
- Replace drawn ball textures with 32-frame rolling cycle + fixed specular
highlight, so marbles visibly rotate as they travel along the path
- Switch from Phaser Containers to a Layer for proper depth-sorted rendering
- Replace hand-drawn frog with assets/images/zuma/frog.png sprite sheet
(2 frames: base disc + slotted overlay for the mouth)
- Add ZumaEditor (/?zuma-editor=1): drag/insert/delete path points, move
frog, tune parameters, test-play, export bank or single level
- Increase BALL_RADIUS 24→32, BALL_SPACING 48→64, and rebalance all tuning
constants (catchup/pullback speeds, explosion radius, frog clearance)
- Extract geometry lint (validateLevel, validateLevelParams) into ZumaLogic
so genZuma.js, verifyZuma.js, and the editor share identical rules
- Rewrite genZuma.js with a Pen class (straights + circular arcs at uniform
STEP=70px) to avoid Catmull-Rom overshoot; regenerate all 20 levels
- Update verifyZuma.js aimbot soak: 8 seeds/level, ≥80% bank clear rate,
star curve calibrated above mechanical play
- Update level data: new coordinates, adjusted quotas/speeds/colors/scores
- Add new background images (background-01.png, background-02.png)
Idle builder units now automatically repair damaged allied structures
and units within their build range. A priority system ensures defensive
buildings are repaired before factories and other buildings. Auto-heal
orders are marked as non-player-assigned so explicit player orders
always take precedence. Builders can re-prioritize targets on a
retargeting cadence, similar to combat target acquisition.
Includes visual asset updates for TA arm and core units/structures.
Adjusts test to isolate passive self-heal from the new auto-heal mechanic.
Bloxorz:
- Rewrite renderer with axonometric projection, rigid 3D box rolling, and continuous face shading
- Introduce new tile types: heavy switches (standing-only), soft switches, hold pads, fragile ground, split cubes, and teleporters
- Redesign all 36 levels using hand-authored ASCII maps in the generator, organized into six progressive acts
- Add design gates to verify solvability, mechanic necessity, and difficulty progression across acts
- Improve input handling with a directional compass, WASD/arrow key resolution, and smooth teleport/fall animations
- Update tutorial to document new mechanics and tile behaviors
Total Annihilation:
- Extend unit/building sight range to cover weapon max range + 2 tiles for improved fog visibility
- Implement crossfade between wireframe and finished sprites for building construction
- Switch to full-color assets by removing army tinting, and update artwork JSON paths/sizes
- Adjust weapon stats (damage, reload times) in rules
- Update sprites documentation to reflect the new visual pipeline
- Add Bloxorz as a new logic game with tutorial support
- Register Bloxorz in games registry, main scene, and game room dispatch
- Preload bloxorz.json artwork data in PreloadScene
- Fix arm-structures artwork path and frame dimensions for Total Annihilation
- Balance Total Annihilation weapon stats:
- Increase tankgun damage (95→145)
- Decrease rocketpod damage (130→80)
- Decrease towerlaser damage but increase fire rate (62→52, 1.4→0.4s reload)
- Decrease towermissile damage but increase fire rate (175→135, 4.5→1.5s reload)
- Introduce configurable victory modes: "commander" (default, kill enemy commander) and
"annihilation" (fight until army can no longer produce)
- Add Laser Tower (1x1, hitscan) and Missile Launcher (2x2, guided with min-range dead zone)
as buildable defensive structures with new towerlaser and towermissile weapons
- Units now hold at weapon range when attacking buildings instead of closing to point-blank,
controlled by new engageHoldFraction constant (0.45)
- Replace center-to-center distance with surface distance for building targets; buildings are
treated as rectangles with true half-extents, improving combat accuracy
- Buildings (towers) now freely traverse and aim in all directions regardless of art orientation
- Commander unit flagged with isCommander; victory conditions validate presence of commanders
- Update campaign missions to use destroyCommander objective; reseed m02 (old seed unwinnable
after combat balance changes)
- Add skirmish setup UI for selecting victory conditions
- Update AI skill ladder verification thresholds to account for engage hold behavior
- Add comprehensive tests for victory conditions and defensive structures
Allow builders to repair damaged friendly units and buildings by
right-clicking them. Repair cost and duration are proportional to the
damage healed (X% HP restoration costs X% of build cost and takes X%
of build time).
Key changes:
- New 'repair' order type with validation (own units only, must be
damaged, requires a builder)
- Separate _repairPower accumulator so repairing a damaged factory
doesn't silently speed up its production queue
- Repair drains energy/mass through the same economy machinery as
construction, including brownout throttling
- HUD hints guide players to right-click damaged allies to repair
- Repair order auto-clears when complete; unqueued orders interrupt it
while queued orders wait behind it
- Visual waypoint color for repair orders
- Comprehensive test coverage in verifyTotalAnnihilation.js
- Initialize lastDamagedTick to -1e9 for fresh units (finite sentinel to avoid JSON.stringify null)
- Add lastDamagedTick to serialize/deserialize so the pause timer persists across save/load
- Add comprehensive tests for self-heal behavior:
- Rate verification (~33% max HP/min)
- 30s pause after damage and clock restart on new hits
- Sustained fire suppression
- No overhealing
- Non-selfHeal units don't regenerate
- Damage clock survives save/load round-trip
- Queue multiple orders per unit by holding CTRL (matching original game)
- Draw colored waypoint chains on the minimap/world for each queued order
- Display queued order count in selection detail panel
- Limit queue overlay to MAX_QUEUE_LINES to avoid clutter in large selections
- Use distinct colors per order type (move, attack, patrol, build, etc.)
- Update hint text and placement UI to mention queueing behavior
- Add verification tests for queue append/replace semantics, consumption order,
and queued build orders
Add a complete Total Annihilation clone including:
- TotalAnnihilationGame.js: Main scene with fixed-step loop, input handling,
camera controls, selection, orders, and match lifecycle
- TAHud.js: Resource strip with flow rates, selection info, build/production
grid, minimap with fog of war, and toast notifications
- TAScreens.js: Main menu, skirmish setup, campaign list, pause menu, and
victory/defeat results
- totalannihilation-campaign.json: 6 hand-authored campaign missions with
escalating difficulty (skill 1→5)
- tools/genTACampaign.js: Campaign generator that bakes terrain from the
seeded map generator
- tools/verifyTotalAnnihilation.js: 13-section end-to-end test suite covering
rules integrity, artwork, economy, pathfinding, combat, fog of war,
map generation, serialization, AI skill ladder, and campaign winnability
- tools/lib/taStubScene.js: Minimal Phaser stub for headless testing
Engine improvements:
- TALogic.js: Swept projectile collision (no tunneling), quadratic AoE
falloff, manual weapon support (D-Gun), unrecoverable elimination, onTick
callback for AI stepping
- TAAI.js: Skill-based economy ladders, simultaneous factory+economy growth,
sticky focus-fire, home defense gating by skill, tune/profile overrides
- TANav.js: fitField dilation for unit clearance, stale fit mask invalidation
- TAWorldView.js: _addWorld for layer ordering, frame-accurate zoom anchor
math, container depth sorting every frame
- TARules.js: autoRangeOf excludes manual weapons, manual flag compilation
Art & data:
- Mayan civilization artwork added to civilization-artwork.json
- Several opponents switched to mayan citySheet
- totalannihilation-rules.json: balanced unit stats, new commanderlaser weapon,
restructured AI skill tuning, formatted JSON
- sprites.md: complete art spec for drop-in PNG sheets
- Registered in gamesRegistry, assetManifest, PreloadScene, GameRoomScene,
and soundtrack service
- Replace flat caps (CAR_CAP, HOUSE_CAP, BUILDING_CAP, WEEK_ROADS) with
per-stage values that scale over the run, preventing the week-6 growth
plateau where the expanded map stayed empty
- Add per-color starvation guards: ensure every unlocked colour has at
least 2 houses and 1 building, even if it means exceeding stage caps
- Allow spawnHouse/spawnBuilding to bypass caps when a colour is
supply-starved or destination-less
- Update bridge placement to handle 1-wide rivers (orientation-ambiguous
single-cell spans)
- Tune PIN_MS_MIN from 3500ms to 2400ms
- Extend Monte Carlo verification to 20 weeks with assertions that the
city grows past the old week-6 plateau
Replace the four-line text yield breakdown with five icon-based rows that draw
total production as icons and show surplus/loss as a signed group. Hovering any
row reveals exact figures and derived facts like growth/starvation timers.
Replace the comma-separated supported units list with wrapped unit chips that
show each unit individually, including veteran status (gold dot) and upkeep
color coding. Chips display a "+N" overflow marker when units exceed the
visible grid.
Extract citySupport() from cityYields() to compute per-unit upkeep in one pass,
ensuring the Shields/Gold rows and unit chips always agree on costs. Add
describeYieldRow() and describeSupportedUnitTooltip() tooltips for the new
visual elements. Add comprehensive headless tests covering icon run logic,
yield identities, government upkeep rules, and tooltip rendering.
- Add CivilizationCityMap.js: draws the 21-tile fat cross in the city screen
with terrain, specials, city sprite, pips, borders, units, and veiled tiles
- Replace fixed 28-row build list with a scrollable window; add shield cost
and turn-estimate annotations per build choice
- Add garrison display: fortified units shown as clickable roundels
- Refactor tileYield() to accept a `notes` array that records each rule's
delta, enabling accurate tooltips that can never drift from engine math
- Extract paintTerrainDiamond() and specialColor() from CivilizationMapView
so the city map and main map share identical rendering
- Add cityCentreYield() enforcing the 1-shield/1-trade market-economy floor
- Add cityTileStatus() for consistent worked/idle/taken/offmap classification
- Add describeCityTileTooltip() with terrain title, yield breakdown, missing
improvement explanations, and status line
- Wire improvementSheet and iconSheet paths in civilization-artwork.json
- Add comprehensive verifyCivilization checks for yield notes, centre floor,
tile status, tooltips, and build list capacity
Introduce active diplomacy where rival leaders approach the player with
requests, demands, trades, and gifts rather than passively waiting.
New CivilizationDiplomacy.js module handles:
- 9 request kinds (joinWar, breakTreaty, borderUltimatum, demandGold,
demandTech, techTrade, ceasefire, peace, alliance) with initiative
tiers so urgent calls to arms aren't drowned out by filler offers
- Cooldowns per (leader, target, kind) plus a per-leader gap so a
leader can't spam different requests to bypass rate limits
- Frustration grudge (0-100) raised by refusals, decaying each turn
and dragging attitude toward hostility through the ordinary war path
- Escalation: frustrated leaders demand compensation, then renounce
treaties at breaking point, with ordinary hostility finishing the job
- Border ultimatum promises checked when pledges expire (double penalty
for broken word)
- Unprompted gold/tech gifts from leaders with high attitude
- Staleness validation so requests the world invalidated are dropped
- AI-to-AI requests resolve immediately through the same pipeline
UI changes:
- AI requests queued on state.pendingRequests, presented via audience
popup at the start of the human turn (one per turn, configurable)
- Diplomacy screen shows ACCEPT/REFUSE with consequence hints until
answered; unanswered requests lapse with half-weight penalties
- New event types: treatyRenounced, pledgeBroken/pledgeKept, aiGift
- Leader dialogue for demands, refusals, gifts, and renouncements
- Tetris Attack menu gets a title art backdrop
Data/infra:
- diplomacyRequests tuning in civilization-rules.json (thresholds,
cooldowns, attitude weights, per-request config)
- Frustration, requestCooldown, lastRequestTurn, pledges fields on
civ state — all backward-compatible with old saves
- Full verification suite covering eligibility, resolution, cooldowns,
frustration arc, serialization, and fuzz testing
- Add japanese-themed city sprite sheet (PNG + PSD) and register in artwork config
- Switch several opponents to cyberpunk or japanese city themes
- Fix hut badge stale display by including tile coordinates in hut events and
repainting affected tiles immediately via repaintFromEvents
- Replace diagonal lattice world generation with hash-based jittered grid:
* Shield grassland now uses balanced 2x2 blocks hashed per position to remove
visible screen-space banding while preserving 50% density
* Special resources placed on jittered blocks with adjacency avoidance,
eliminating clumping and barren regions
- Update sprites.md paths and status markers to reflect completed sheets
- Expand verifyCivilization checks for shield density range and special placement
quality (no adjacency, balanced windows, no screen-column alignment)
- Update Tetris Attack dialogue with control instructions and typo fixes
Refactor Stage Clear narrative from battling opponents to helping friends.
Update character poses: friends cheer on clears and fret during danger.
Implement multi-line intro cutscenes with step-by-step progression and random background art.
Switch dialog to randomized arrays (introLines, winLines, loseLines).
Add new sound effects for Beth and Jerry.
Update validation and documentation to match new data structure.
Detect when a player shortcuts across geometry and skips checkpoint gates
by monitoring the spline projection delta. When the player jumps past
the configured skip threshold, they are teleported back to the last
legitimate checkpoint, shown a blinking "CHECKPOINT MISSED" banner,
and given a brief invulnerability window.
- Add checkpointMissSkip and checkpointMissMs config values
- Implement delta-based gate-skipping detection in kart logic
- Add HUD banner and sound feedback for missed checkpoints
- Make player sprite blink during the correction window
- Add verification tests for detection, correction, and clean-race false positives
- Make Tetris Attack portrait frame half-transparent
- Replace hard-capped difficulty curves with exponential ramp function
that continues scaling deep into endless play without plateauing
- Reduce base speeds and shot counts for more deliberate gameplay
- Increase flipper, fuseball, and pulsar speeds for more pressure
- Flipper AI now chains hops toward the claw instead of resting,
making it a true pursuer rather than a shuffler
- Change zapper to refill +1 per level instead of full reset, making
charge management meaningful
- Death no longer resets the board: only enemies within threshold t
die with the player, others remain mid-climb
- Improve enemy shot hit detection with lane distance check instead
of exact lane match
- Add advanceShots() helper for cleaner shot advancement logic
- Update verification tests for new mechanics and difficulty curves
- Add michael background sprites and update tetrisattack characters
Restructure Tetris Attack Stage Clear from "clear all target panels" to a
multi-stage round system with a sliding boundary line.
Gameplay changes:
- Each character now has 5 stages instead of a single match
- A CLEAR line appears after a set number of rows rise, then rides the
stack upward; the objective is to clear everything above it
- Clearing a stage advances to the next: same board, faster speed, fresh line
- Stage progress is saved to localStorage; characters unlock sequentially
- Added a stage select screen with progress squares per character
Logic changes:
- Replaced `targetsTotal` with `clearLine` tracking and `countAboveLine`
- Added `advanceStage()` to resume play on the same stack one speed level higher
- Win condition now checks `countAboveLine() === 0` instead of target count
- Removed `target` flag from panels; panels below the line are irrelevant
- Continuous speed ramp via fractional `speed` per stage
UI changes:
- Clear line drawn as a pulsing bar with "◀ CLEAR" label outside the board
- "CLEAR LINE!" announcement on appearance, "STAGE N CLEAR!" banner on win
- HUD shows stage number instead of panel count
- Game over offers "Retry Stage", "Stage Select", or "Menu"
Asset changes:
- Backgrounds renamed to `background-{hero}-r{stage}.png` (5 per character)
- Lazy-load backgrounds per round instead of preloading all 30 images
- Updated tetrisattack.json with `stagesPerRound`, `stageSpeedStep`, and
per-character `clearLineRows`
Tests:
- Rewrote stage clear soak tests for the new mechanic
- Added stage round progression, speed ramp, and board preservation tests
Implement the full Tetris Attack clone with three game modes:
- Endless: clear panels as the stack rises, speed increases with levels
- Stage Clear: defeat 6 character opponents (Beth, Jerry, Michael, Steve, Victor, Klaxon) in sequence
- Puzzle: solve 24 pre-vetted puzzles within move limits
Core engine (src/games/tetrisattack/TetrisAttackLogic.js) is a pure, deterministic
state machine with match detection, chain propagation, gravity, and scoring tables
matching the SNES original. Includes a headless verifier (verifyTetrisAttack.js)
testing match detection, chains, gravity invariants, top-out, puzzle solvability,
and seeded determinism.
Art is fully optional via drop-in spritesheets (spec: sprites.md); procedural
fallbacks draw 16-bit-style panel icons with distinct shapes for colorblind access.
Puzzle bank generated by genTetrisAttackPuzzles.js and verified as solvable within
optimal move counts.
Shared nintendo soundtrack reused via soundtrack overrides.
Introduce a unit unlock system that progressively grants access to new
unit types as the player advances through the campaign. Each mission
specifies which units each army can build, starting with basic units
and unlocking MD Tanks, Rockets, Anti-Air, Missiles, Lander, Cruiser,
and eventually the full armory.
- Add unit sprite sheet (advancewars-units.png) and artwork config
- Implement unlock validation in production and build options
- Add tutorial dialogue from Ethel explaining new mechanics and units
- Balance AI difficulty by reducing skill levels and aggression
- Adjust capture weights for more balanced AI behavior
- Add introductory city capture mechanic in first mission
- Update verification tool to support unlockedUnits
Implement a full Advance Wars clone with campaign (20 missions) and
War Room skirmish mode. Includes:
- Headless game engine (AdvanceWarsLogic) with complete AW1 rules:
terrain movement, combat, capture, production, transports, fuel,
fog of war, CO powers, and multiple objective types
- AI opponent (skill 1-5, aggression/capture tuning) with BFS
pathfinding, threat evaluation, production counter-tables, and
fog trap awareness
- Canvas-rendered map view with procedural stand-ins that can be
replaced by drop-in painted spritesheets (no code changes)
- 11 playable COs with unique day-to-day modifiers and powers
(Hyper Repair, Lightning Strike, Tsunami, Meteor Strike, etc.)
- Campaign briefings with typewriter text and opponent portraits
- Comprehensive headless verification suite (rules, combat formula,
pathfinding, economy, capture, fog, CO powers, soak tests)
- New assets: terrain/building sheets, adventure music tracks,
game icon frame 86
- Refactor SpireClimb and SWDBG to use the shared soundtrack service
- VictoryCamDirector: cinematic post-race camera system with shuffled
shot types (chase, orbit, front, trackside) and hard-cut transitions;
player can press ENTER to skip.
- Engine audio: per-racer engine hum (heavy/fast/medium) with pitch
tracking based on kart speed; engine-start sound at green light.
- Star power loop sound that stops when star expires.
- Positional audio: AI kart sounds (spin, hit, flatten) scale volume
with distance from player.
- Enhanced event sounds: item-use, boost, EMP, squash, bump, coin,
star now play appropriate SFX.
- Player kart autopiloted after finishing for victory-lap vignette;
race phase waits for entire field (up to 90s safety cap).
- EMP now emits target list for per-target shrink sounds; squash
collision emits event.
- Animated race results screen with staggered row reveals.
- Animated cup standings with running point counter and position
arrows; tweens rows to new ranks.
- Podium reveal: 3rd → 2nd → 1st staggered with confetti, count-up,
and CRT pulse; winner speech plays.
- Mode7 camera now tracks height and focal length; setCamera accepts
arbitrary poses for cinematic shots.
- New audio assets: engine-start/heavy/fast/medium/rev, kart-coin,
kart-flatten, kart-thump, kart-shrink, kart-spin, kart-hit,
kart-shell, kart-star.
- Replace hardcoded 'warriors' default with pickNextBuild() for both
founded and captured cities
- Captured cities now adopt the new owner's tech level when selecting
their default unit (e.g., Phalanx if Bronze Working is known)
- Add verification tests for tech-dependent defaults on founding and capture
- Add Coinage (1 shield → 1 gold) and Public Works (2 shields → 1 food)
special build options for cities, with remainder carry logic in shieldBox
- Update AI to fall back to producing gold or food instead of stockpiling
redundant defenders when nothing else is available
- Fix mid-build detection to check build.type before comparing shield progress
- Add City Screen UI for special builds: display gain per turn, color-coded
rows, and tooltips
- Only apply class-switch penalty when switching between unit/building
production types
- Add verification tests for coinage payout, public works remainder carry,
and AI special build fallback
feat(superkart): fix player kart scale + add missing backdrop images
- Compute PLAYER_KART_SCALE from MODE7 parameters instead of hardcoding,
keeping player and AI karts consistent at the camera's follow distance
- Wire up previously null backdrops: volcano, scrapyard, swamp, speedway,
nightcity
- Add beach theme artwork and register paths in artwork JSON
- Implement AI rubber-banding that scales AI top speed based on gap to player
- Configure engine classes with varying rubber-band strength (Cruiser most forgiving, Turbo least)
- Balance racer stats: boost Kona top speed, reduce heavy racer accel/handling
- Update verification script to validate new rubber-banding configuration
Complete kart racing game featuring 12 procedurally generated tracks
across 3 cups, 9 unique racers with distinct stats, headless physics
simulation, and a secret track editor (?superkart-editor=1).
Core features:
- Mode 7 ground renderer with parallax horizon backdrops
- 12 hand-tuned tracks (speedway, beach, swamp, scrapyard, volcano, nightcity)
- 9-racer roster with balanced archetypes (all-rounder, drift pirate, etc.)
- Headless race simulation for deterministic AI and headless verification
- Item system (bolt, seeker, oil, turbo, overdrive, emp, coins)
- Position-weighted item roulette and rubber-banding
- AI opponents with skill-based driving and stuck-recovery
- Full track editor with live preview, validation, and export
- 275 verification checks covering schema, physics, AI soak, and determinism
Data files: data/superkart-racers.json, superkart-rules.json, superkart-artwork.json
Game data: assets/gamedata/superkart/ (cups.json + 12 track files)
Tools: genSuperKartTracks.js, verifySuperKart.js
- Introduce difficulty-based combat multipliers and veteran promotion chances (Chieftain/Warlord eased, Prince+ neutral)
- Randomize leader selection on setup screen and add dynamic portrait with pick speech
- Replace inline hover text with a centralized Tooltip component for tech tree, foreign cities, and buildings
- Add descriptive flavor text for governments and terrain improvements
- Add building completion notifications with a "VIEW CITY" action button
- Expand deferred city attack cinematics to cover explored rival cities
- Improve Tempest flipper AI to scale lane-flipping chance/cooldown with level and enable climbing flips
- Add verification tests for difficulty combat modifiers and veteran rates
- Add Tempest (Atari 1981 vector arcade clone) with full simulation logic,
Phaser rendering scene, vector font, and headless verification suite
- Register Tempest in games registry, main scene list, and game room dispatch
- Add reusable Tooltip UI component for hover-based information display
- Add Civilization unit/building tooltips in city screen and map hover
(CivilizationTooltips.js with flag and effect descriptions)
- Update Civilization click handling to distinguish hover-only from real
click targets via hoverOnly data flag
- Update civilization-units and game-icons assets
- Add bottom-right status log panel with scrollable entries, word wrap,
mask clipping, and mouse wheel scrolling; cap at 60 entries
- Replace toast popups with announceStatus() for major events (war, tech,
first contact, city founded, trade routes, huts) — centered modal with
CONTINUE button that animates into the log; supports queued popups and
custom onDismiss callbacks (e.g. first contact opens diplomacy)
- Add smooth panToTile() tween for camera movement when selecting next unit,
refactored clampPan into panBounds() reused by both clamp and tween
- Add classic city sprite sheet (civilization-cities-classic.png) and
register it in artwork JSON and asset manifest
- Replace circular civ rings and selection ring with isometric ellipses
matching the 2:1 tile ratio for better depth reading
- Paint tile neighbors in ascending c+r order during repaintTileAndNeighbors
to prevent tall features from being overwritten by lower-sum neighbors
- Stop panTween on pointer down to avoid conflict with manual dragging
Allow each opponent to declare their own 2-3 starting technologies in
opponents.json, independent of their civ trait. During game creation,
personal and trait-based starting techs are unioned (deduped) so
pioneering leaders with overlapping lists don't double-grant.
- Add optional setup screen background image (civilization-setup-bg)
- Update leader detail panel description to list personal starting techs
- Deduplicate trait + personal techs via Set in CivilizationLogic
- Add validation for startingTechs arrays, tech existence, 2-3 total count,
and variety across leaders in verifyCivilization
- Add integration tests for personal tech granting and overlap deduplication
Introduce civTraits data structure with 8 traits (scientific, industrious,
commercial, philosophical, zealous, mercantile, pioneering, wealthy) that
provide science/gold/shield multipliers, starting gold, and starting
technologies. Assign each opponent a trait in opponents.json.
- Apply trait bonuses to starting gold and grant starting techs during
game creation in CivilizationLogic
- Route trait multipliers into cityYields for science, gold, and production
- Add a leader detail panel to the setup screen showing name, trait name,
and description, updated live when selecting leaders
- Add validation for civTraits in CivilizationRules (multipliers positive,
starting techs valid, etc.)
- Add verification tests for trait application and city yield multipliers
- Nudge unit sprite position 5px down for better tile alignment
When a city cannot complete a build (e.g., size < 2 for settlers),
shields were accumulating past the build cost, showing confusing
values like "60/40 shields" or negative turn counts.
- Cap shieldBox at buildCost each turn in processCity
- Clamp displayed shields to min(shieldBox, cost) in city screen
- Add tests verifying shield capping and stalled build completion
