Fun little minigame. No idea if you'll come back to it in the future, but here's some comments anyway
- Having menu advancement tied to 'any key' is annoying, since I accidentally skipped the final screen by trying to jump
- More spread on the 'x' shot would be nice. You have to inch into enemy lasers to hit them with it.
- Enemy lasers sometimes fire before they're even visible on screen. You should check whether or not they're in the camera frustrum before their attack windup.
- I completely forgot the 'c' button did anything. Might be nice to have a reminder when it's usable
- Level system didn't really feel relevant except at low levels when you can't spam the 'x' button. After you pass a threshold there's no way you'll ever bottom out on mana.
- The game doesn't do anything to force you forwards. The bountiful pickups mean that just chilling out for a bit and breaking boxes will give you enough health to tank the next few stacks.
