My Instant Game: Cat Gunner: Super Force
I think your game is so cool! Do you do all your graphics yourself?
I can though say, that some effects you are using are not supported on iOS, so they will just be a strange noise. Also when I finished the first stage, the game got stuck while loading. So the only thing to do was to close it... :(
