The concept is fun and very well presented. It's great when you hit the jumps but I found the physics quite unpredictable. You could change the dice to a different shape as the levels get completed (cube, 5 sided, 4 sided, 3 sided, coin) to avoid the rerolling problem. Alternatively if there was something you could gain from repeating a level could be cool to incentivise that, maybe extra re-runs or a modifier.
Well done
