Really liked this one, the art style is unique and has some really quite sound effects as well.
Gameplay is simple though a little slow - is still enjoyable. The enemies in the first round are a bit overwhelming, maybe introduce them slowly?
Also some UI could help with rounds and stuff, as I originally thought the game ended after wave 1 enemies. So some UI/UX could be helpful to the player.
Also the dog is too fast, and I could not bring myself to punch it.
