It's an interesting concept. Keeping the lemon on the skateboard, especially on the ramps, was challenging in a fun way. I also liked how it restarted quickly after a game over, to keep you in the flow.

I think if the camera didn't rotate with the skateboard, it would be more playable. I assume it's parented to the skateboard? Maybe add a script that just copies the position, so it lurches around less.
