Asteroids Clone Progress

I've made a good deal of progress on my C++ and SDL based clone of Asteroids. A friend of mine, Mike Sovey, saw the prototype I had online and sent me a copy of the game with graphics he made already implemented, and when I opened it I was very "wowed" for quite a bit. Since then I've been working on finishing it up, and presently I have a high score table working in code (no display) and momentum, as well as a series of other tweaks and add-ons to the original. Click somewhere in this sentence to download the latest build. Please tell me what you think of it, I'm anxious to get some feedback. Finished game should be done by Wednesday, so keep an eye out for it.
