Hi, I loved the animations of the player. The game feels nice to play and you nailed the groundpound effects. I think it fits the theme and the limitation perfectly :D.
I had a small bug where I fell in the void and couldn't escape or respawn but maybe I just didn't undestand something. My only recommandation would be to maybe make shorter levels or cut them with some sort of checkpoint system because it can get a bit frustrating after some time.
Other than that I think it's a fun game, great work!
