a fun and simple formula of getting as much points as possible before dying. The inclusion of the highscore-list is definately the strongpoint of the game, adding an enormous value to the enjoeyment.
However i do think that you should've skipped the tricks. They don't fill any real point and they all give the same score, making it unnessecary to even use more than one. Personally i only used the frontflip on "S". You should've just cut it down to a simple jump button.
Also i got this feeling that the jump wouldn't work sometimes. I just kept sliding and he'd go down the slope despite the fact that i pressed the button. But maybe I'm just imagining it...
