Update wave timing from 5s/10s intervals to 30s/60s intervals for game progression
```

The commit message summarizes the change where wave timers were adjusted from 5-second and 10-second intervals to 30-second and 60-second intervals, effectively slowing down the game progression. This change likely makes the waves less frequent and more manageable for players.

The changes modify:
- Wave 1 trigger time: from 5 seconds (5000ms) to 30 seconds (30000ms)
- Wave 2 trigger time: from 10 seconds (10000ms) to 60 seconds (60000ms)

This adjustment increases the time between waves, potentially making the game easier or giving players more time to prepare for each wave.
