I have a knot in my fingers now. And in my brain... :D Jokes aside, great idea and nice presentation. I just had some troubles that sometime the game wouldnt recognize more than two inputs at a time.
It looks like the problem is that W is some sort of hotkey and while pressed you can only press 2 keys, and with that the game is almost impossible to play and I still don't know what to do about it because it happens only to some people. Anyways thanks for playing. (:
