One thing- for a simple game it's well polished. But try putting the .bmp quality or whatever it's called up under publishing settings to smooth out some of those rough looking edges. Also- you've used no color except for the red on the mute button, kinda seems a waste, I don't believe you couldn;t come up with any better ideas for that =P, look how I did it on my game spOces+. Good game :]. (since it's your first game I upped my rating to 5)
This is the terrible bones of a game. A bad idea, badly implemented with only the absolute minimum to even allow it to be classed as a 'game'. But just because it's physics based and made by armorgames you guys lap it up and it gets a 4+ rating. ofcoure. 1/5, try again -__-
