Solid game but feels a bit lacking in terms of difficulty. Some issues I saw when playing:
- The laser can be used when it is not turned on. If you turn off the laser and then immediately try to use it again, you can deal damage without the laser being visible.
- The time between waves feels very slow at the start. Maybe have the time increase the longer you play to speed up the start?
- There is very little reason to use anything other than the large laser. A cool-down of some sort would probably help to incentivize use of the lighter attack.
