Charming idea! I think one of the main things I felt was that the stamina gauge was a bit uncomfortable, because after a time of jumping and attacking, there wasn't really anything for me to do besides stand still and wait for it to come back. I think it could help if it recharged quicker, didn't apply to both jumps and attacks, or some balance of the two.
Besides that, I liked the powers and the implementation of the theme! It's a clever way to tie the player and the enemy together, and makes the world feel really interactive. Great work!
