Great game! The movement feels really satisfying when you nail the momentum and the animations, particles, SFX, and BGM all come together to create an impressively polished experience for something created in such a short amount of time. I think it was a really clever strategic decision to divide the game into different "sub-levels", which makes the game maybe slightly less "foddian" as the previous commenter said but actually ensures people play and complete your game in one short sitting instead of ragequitting, which is important for a jam with such a short rating window.
I think a fun feature would be some sort of positive feedback if you did a frontflip/backflip in the air, just for that extra coolness factor that's found in your typical skateboarding games.
Overall, really excellent submission!
