Pretty solid game. It had a retro cyber aesthetic (I can't think of the word for it) in the visuals and audio that I enjoyed. The shooting seemed a little off to me, both because bullets only appeared sometimes and it seemed like they hit on the upper-right corner of the cross hair instead of the center. I agree with Griddolini about the movement seeming slow, but then I rocketed forward when I jumped, making me think there's too much friction.
The fact that you got a FPS working in this short time is impressive!
