This is pretty fucking fun. A lot of potential here.
As Gator has said, tricks on the right stick would be nice though I found switching between stick and d-pad with the left hand wasn't an issue.
Holding the jump button needs some indication like the character crouching even lower to get ready to jump. As it is it feels like holding it does nothing until you release it.
There doesn't seem to be any penalty for messing up a trick other than losing points. You get that roll animation but it doesn't slow you down or anything.
Animations should be snappier. The rotations in particular feel too linear.
The yellow/orange/red(?) boost indicators coming from the hands seem a bit weird. Wouldn't be board make more sense?
