Soo ummm... This game was absolutely amazing. And thats an understatement. The controls were tight, and the action kept me entranced the entire time (and the only reason I stopped (making sure to bookmark the page) was because I had to rate it and play other games (and I definately should not have been playing it on a laptop)). The amount of stuff you got into it in only 10 days is unbelievable as well. And the difficulty was terrific.
On the graphics side, I was annoyed by the background being in such a different art style to the foreground, but thats just a question of preference I guess.
Oh, and the idea of putting a demo in the menu was great. Definately gonna steal that
