Oh, this is fun. The idea of being the janitor in a platformer game and having to fix the stage before the protagonist gets there is novel. The level design was good, though I found level 8 a bit frustrating due to how easy it is to get stuck on your hat. Was the hanging by your hat thing intentional? It was useful sometimes when going up, but mostly irritating when trying to go down. Overall a really smooth and well executed platformer.
