I really like the idea of this game. And I disagree with what others said. It doesn't matter if it is "basic" the idea is cool and it would be nice if you work on the game after the jam too :)
The music is amazing and the controls are super easy and yet extremely frustrating when I accidentally cool 4 cats at once (which is good because you really have to wait for the right moment). Some sound effects would be cool :D
Two things that I didn't like that is that the game takes really long to load (with your name and title screen; I think it would be better to have them on one screen). And the other one is that the canvas is kind of too small for 20 cats (but also this is the challenge, right? :D)
