Cool demo, liked the music and most of the graphics but the different sizes of the pixels in the hud and the projectiles compared to the rest of the game made them quite inconsistent. Movement works fine, the jump is pretty floaty though. Shooting could be better, it's weird how it happens when you release the shooting button and even then it's delayed. I also think that it shouldn't be done with the mouse as you can't aim with it. One more gripe, the camera is very close so the character is huge and it's hard to see what's around. Overall this looks and sounds cool but there are many things that could be improved in the future.
