Very cool work, I enjoyed playing. Clean presentation, easy to understand. Don't think it's a problem that the game gets hard: a challenge is good, and makes people think about the mechanics. Speaking of which, I think stunning the enemies rather than killing them was really what sets your idea apart from any typical platformer. Made me think about platforms in a different way, which I enjoyed. Probably my favorite choice you made was to NOT put the player all the way at the start of the game when they got hit. Being right back on the same challenge I was trying to beat very much encouraged me to keep playing.
