The style of this game is very cute and incredibly cohesive, and I really like the direction you went with the gameplay. I did find the mechanics to be precise to a point of it being frustrating, and I was constantly having to redo rooms due to small issues with spacing or timing. As others have mentioned, the jump not triggering near ledges was a big sources of that. I think with some refinement in that part, it would be an awesome platformer with a really cool gimmick. Coming back through the rooms with a new approach is very satisfying.
