Rock Blaster!

This is your basic Atari-style game (*cough* astroblast *cough*). It has neither bells nor whistles. Use the arrow keys to move, space bar to fire. Enjoy the original graphics, music and sound effects!

I wrote this to test out a framework for pygame after reading a few of the excellent pygame books out there. Sprite movement is done through vectors and screen states are represented through classes. It's an interesting way to organize simple games, but I'm not convinced this is the most natural way to do things.
