Meh...
It was kinda fun. It needs some sort of new dynamic. Something that'll take the game from holding down the right key to executing a string of commands to gain a further boost. I liked it for what it was though, a game where you do a stunt on a motorcycle. Very easy though. I'd say some more advancement in this game and you can actually turn it into something. i.e. some sort of trick-point system, new tracks, more vehicles, etc. Also try to add in some more sound. Nice job though.
