This is a cool idea for a game. I really like it!
However, I find it a bit difficult to play. I got lost at first as there is no indicating where you are and how fast you are moving when the background is all black. Didn't notice that you had to shoot the red thing for at least 20 minutes. Having to shoot it twice was a real pain. When the game starts you always shoot down first, then you have to move your mouse 360 around the character to shoot down again.
With some polish this could be a great little game.
