Choppacide has went through several changes since I first submitted it. I have tweeked the controls to make it a bit more manuverable. I also added the "F" key as a fire key because it seems that many linux windows managers handle the space bar odd, and I was loosing control of the ship if I pressed the space bar first. 

I am working on a few visual improvements for the final version of choppacide. I would appreciate any feedback on the game.
