Not to bad. Needs (alot of) work though.

There's just lots of shooting going on and not much of a game here. With lots of tweaking, it could be turned into an Asteroids-like game.

Very nice! Add some more actual game play, a story and make those baddies less violent and you have a really nice game! However, I had to tweak the source a little to let it compile with MinGW32 - it's a little unportable (no big deal).
