This game is so fun. The art style, the weapons, the abilities. Its just perfect.
The only thing is that I feel like there should be a level system or something that measures progression, other than just endless enemies that build up (and decrease frame rate). I really hope you develop this game further as everything about it is destined for success, it just needs some tuning. Also the controls could be clearer.
If possible could you check out my game? Any feedback would be appreciated.
