Control Shift IPhone Game Player Ship

ControlShift is an iphone game we put together in 19 hours last Saturday. It's like space invaders with words, and you shoot the invaders using your iphone keyboard. While the current version was waiting for review, I spent some time designing additional sprites, bosses, and programming some extra game mechanics.

I'll add the artwork and progress here as it comes along.

The shot above shows our courageous player ship. Any feedback on how I can expand the color scheme would be helpful!
