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
Advance Wars:
- Add HP override system (seed/set/clearHpOverride) so units show correct
HP during enemy-turn replay until their battle animation plays
- Redesign river/road channel rendering with layered depth: rivers get
deep channel, light core, and ripple crests; roads get concrete shoulders,
asphalt, and dashed centre lines phase-locked to tile seams
Tetris Attack:
- Add character sprite sheet and per-host background images (beth, jerry,
michael, steve, victor, klaxon)
- Declare hero background assets in manifest; scene falls back gracefully
when art is missing
- Update characterSheet path in tetrisattack-artwork.json
- Track `_prevRow` on falling panels for interpolation during animation
- Add `_justLanded` flag to introduce a settling frame after panels land
- Interpolate panel Y position from previous row for smoother fall effect
- Defer match detection and chain-end logic until after settling frame
- Update assets: new background-menu and main-title images, update existing sprites
Units doomed to die later in a pre-resolved enemy turn were being removed
from the board prematurely during sync, before their death animation could
play. Now:
- syncUnits only prunes dead views on actual army elimination, not on
mid-turn CO powers that would kill units later in the same turn
- Added 'loaded'/'joined' event handlers to remove views when units merge
into transports at the correct animated moment
- setUnitVisibility skips views whose units are already gone from state,
preserving mid-replay sprites until their event fires
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.
Import and play day banner animation when transitioning between turns
in Advance Wars game. The banner displays the current day number and
plays before allowing the next turn to begin, providing visual feedback
for day progression. Added safety check to cancel animation if scene
changes during playback.
- Add HP text readout to battle animations showing 1-10 scale HP
(matching Advance Wars' classic HP display), with smooth tweening
- Extract cursor drawing into procedural texture, keeping it independent
of the UI sheet
- Add advancewars-ui.png sprite sheet and update artwork config
- Assign battle sounds to each unit type (gunfire, tank, cannon, missile, etc.)
and play the appropriate sound on attack/counterattack in battle animations
- Add per-unit-type movement sounds (march for infantry/mech, engine-fast,
engine-heavy) that loop during move animations and stop cleanly on completion
- Play jump sound during capture animation hops and activation sound on capture
- Play explosion sound when units are defeated in combat or crash
- Lighten unit tint relative to buildings so units remain visually distinct
when standing on captured buildings
- Add new audio assets: battle sounds, march, 8bit-jump, and update battle-tank
Replace the solid-color ground rectangle in the capture animation with a
proper terrain backdrop matching the ground the building sits on (plain,
shoal, etc.). Extract battleBgFrame, ensureBattleBgSheet, and add a new
groundBgFrame helper that maps building types to their underlying terrain,
avoiding duplicate building rendering since the building is already the
main squishing prop.
Introduce a new battle background spritesheet (advancewars-battlebg) that
displays context-appropriate backdrops behind each fighter during battle
cut-ins. The backdrop is selected based on the terrain/building type the
fighter is standing on (city, base, airport, port, plain, wood, mountain,
sea, reef, shoal, river, bridge, road, hq).
- Add battleBgSheet to artwork.json and asset manifest
- Implement playBattleAnim() backdrop system with terrain lookup
- Provide procedural fallback matching the real sheet's frame map for
art-free playability

- Document the 14-frame sheet spec in sprites.md (256×256 cells, 5 cols)
Introduce a breathing pulse effect (red fill + white border) for attack
target tiles to draw the player's eye when in "must pick a target" fire
mode. The previous static tint is preserved for the indirect-range preview
shown while a unit is merely selected.
- showAttackTiles now accepts optional { pulse: true } parameter
- Added tween-based animation with Sine.easeInOut breathing effect
- Properly clean up pulse tween in destroy() and clearOverlays()
- Updated AdvanceWarsGame to pass pulse: true when showing targets
Introduce a cinematic capture animation when a unit captures a property:
a small window shows the capturing unit hopping atop the building, which
then squishes down to reflect remaining capture points (or pops back up
in the new owner's color if the capture completes).
- Add AdvanceWarsCaptureAnim.js with the full cut-in animation sequence
- Display remaining capture-points as a strength number on partially-
captured buildings, tinted toward the owner's color
- Add `before` field to capturing events so the animation knows the
starting HP
- Support partial unit sync so units are revealed action-by-action
during turn replay instead of snapping to end-of-turn positions
- Add depth bias so units always render above buildings on the same tile
- Add new unit sprite sheet (advancewars-units.png/psd)
- Slow down all battle animations for better readability:
- Attack, flash, death, and delay timings increased
- Unit movement animation duration increased (70→180ms)
- Explosion animation slowed down
- Post-turn wait time increased (140→300ms)
- Merge props and units into shared Y-sorted "actors" depth band
- Buildings and units now sort correctly by screen row
- Move/attack overlays remain below actors for proper decal rendering
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

- 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
Introduce game-specific music overrides using the soundtrack service.

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).

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.

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 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

Add audio feedback for combat events by introducing unit-specific sound
effects that play during attack animations. Each unit in civilization-rules.json
now has a battleSound property mapping to appropriate audio assets. Adds 10
new MP3 files (arrows, cannon, catapult, gunfire-classic/modern, helicopter,
missile, submarine, sword, tank) and integrates playback in CivilizationMapView's
combat lunge animation.
Lower the minimum distance requirement for establishing trade routes
from 8 to 6 tiles, making caravan routes more accessible. Also refactors

- 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

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

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
