quit nice. make your asteroids fall a bit faster and maybe make them (and your planet?) a bit smaller. have a look at the coalition thingy of your planet or asteroid. something is to big. died several times although I wasn't even close to an asteroid. at first it looked like the smoke killed me but when an asteroid was passed by I could enter the smoke. redraw your earth, the asteroids are better looking :). all in all a very nice little thing to build a bigger game on. keep continuing this.
feel free to try-out and rate my game.
