Looks very nice; I especially love the particle effects when moving the ship or blowing up asteroids. Music is repetitive, but it's at least fairly quiet so it doesn't get obnoxious.

Otherwise, it's a solid version of Asteroids. Controls about as well as I could expect it to, and though the playfield is a bit cramped, it's not too bad if you stay away from the edges. Not sure if there's a twist to it, since I can't seem to get past level 1 (I was never that good at og Asteroids, to be fair).
