Thanks for you feedback.
- The nuke blast effect (the one that falls to the bottom of the screen) does damage. But maybe need to up its damage more.
- Auto-lock when upgraded increases damage, and at higher levels can lock multiple targets, up to a maximum of 3 simultaneously.
- Freeze/Ice have bullet cancellation effect from level 2.
- Rockets should be one of the highest DPS at later game.
- Sound is from browser audio (.mp3 and .wav). You might need to allow sounds when prompted by browser permission.
