Awesome, I had lots of fun with that.
A great re-make of the original asteroids, with improved controls, graphics, music and ofcourse all those nifty features you added such as "health" and "fps". Nice.
Suggestions:
A pause button: While playing this I actually had to get up to answer natures call but I didn't want to just leave myself out in the open with tons of asteroids dlying around which as you might imagine made it very uncomfortable and not as enjoyable.
And, while I was holding down the spacebar to shoot, I noticed I could not turn whatsoever and I would have to release the spacebar to turn and if I didn't it would make that annoying *beeeeeeeeeeep* sound on my computer.
Overall I though this was well done. The main menu looked very professional and this game as a whole was very organized. Great job!
