The graphics of the game are appealing, but the lack of sound effects and music, makes the game fall a bit short :< The game doesn't stick too close to the theme, but I guess it can be fun if you had another player to play with c:
Flashy colors and cute cats faces! :3 I agree with XtremePrime, the lack of sound is quite disturbing. Why don't you add it? You can upload the fixed version, so the people can play your game with the sound and enjoy it more :)
I'm guessing that this game wasn't quite finished (judging from the random "Shake Screen" button and how P1's up arrow somehow affects the camera, but nothing else).
Game looks good. What's there works pretty well (though the scoring seems to trigger twice from time to time -- can't tell for sure without seeing the source, but I'd guess that it's due to the target spawning on the same spot.) Good work
