The whole sleep/wake state mech is actually a cool idea. I didn't realize at first that the rooms were changing states, but once I got it, the puzzles made a lot more sense and it got more interesting. Shrinking in the washer, pumping yourself bigger, electrocuting yourself ot power those mechanical sheep platforms; it's definitely creative. There are some clever ideas in there. The hand-drawn visuals are nice too. They have charm.
The spiral staircase part was interesting, glad I was rewarded. I kept trying to access that area but then the game sent me away to the clouds because I messed up getting shrunk, so glad I was able to make it back there.
Overall though, once I understood the core mechanic, I appreciated what it was going for.
