Personally I don't usually like platformers like this. Honestly, this was too difficult for me. However, for the number of different interacting elements I wouldn't be surprised if this is the best game in the jam. 5 stars for sure.
My main potential advice would be that if the obstacles were stunning rather than lethal I'd be much more likely to play a level again and again to get a faster time... perhaps that could be an optional "accessibility" mode (if not the default setting)? It wouldn't be unbalanced for high scores, because having to stop moving for 2 seconds would already invalidate a run either way.
