I had a fun time with this one. The artstyle was very interesting and the main mechanics made a nice little puzzle game.
It would have been nice, if you had some sort of indicator which controls were enabled and disabled, since the collectible actions only tell you what they add and not what they take. There were also a few levels, where you had access to controls you probably shouldn't have.
But yeah, short, simple, fun and appealing. Can't ask for more in a game.
