Skateman on the splash screen looks cool but you should consider putting it on the sky colored background as it is barely noticeable where the skateman ends and the purple background begins.
In-game sprite doesn't really match the quality expectation set up by the drawing in the splash screen. But don't get me wrong I'd prefer playing the game with the in-game sprite (provided it had some animation with it)
It's extremely hard to land on the other side and still stay on the board, much less do tricks.
I like the idea of only one jump and I'd like to see this game with a bit more polish, less focus on getting across the chasm and more focus on the tricks.
