Mute and pause are always essential to a popular game, I like the art, did you draw it or did it come as part of this tutorial? Good for a first game anyway.
The constant crazyness.com angered me, and this game has been done before, like all games I realise, but apart from making it a car instead of whatever the original was, no change at all.
Surprisingly addictive, some more modes, slightly improved graphics, and some background music (everyone will mute it but that's not the point :P) and this could be into 4 stars for me.
