Slow progress

Unfortunately, due to finals in other classes, I haven't been able to do too much work on the game. On Saturday, I worked on a weird glitch that popped up with the shields. For some reason, the enemy's shields are being drawn much more opaque than they should be, but the player's shields are drawn normally. I worked on that for a while, but then decided it was more important to start working on AI, so Felix and I talked about how to implement each AI state.
