This was neat, and I also immediately thought of Rhythm Heaven when the theme was announced, haha. The game was fun but sometimes things behaved in ways I didn't expect and it wasn't clear why. For example sometimes when I push the nut horizontally it rotates but sometimes it doesn't; it was never clear why that was to me. In the level with 3 launcher thingies the screw would not activate the launcher if the nut was directly to the left, even though that looked like it could have been a valid solution.
