its a really cool game but it could use a few improvements.
Unlocking upgrades is a good idea. I would also like to see a feature that would allow us to take a picture of the floor so we can look at it later.
if you have troubles beating an opponent: resize the window so the chamber and the guy's head is on the edge... you can move the mouse out of the window with out pausing the game.

I completely agree with this
"Simple to a fault. The star lines always face the same way, there's no real challenge beyond a insignificant test of your precision mouse-moving near the end of each level. I must admit it's a beautiful game with an interesting concept, and for that I give it a 4/5, but if it had a bit more depth or challenge to it it could have earned a 5/5."
