Pretty straightforward. Nice changing background color. It took me a minute to figure out what was going on with the exclamation points though -- it seems like those should disappear once you've collected them. It would be nice if there was some way to play the game well enough that you keep going and going -- as it is I feel like I'm going to lose pretty quickly no matter what.

Nice and straightforward. Not exciting as is, but quite potential. I thought it would be cool if you posted highscores as the color they got to.
