I really like the concept for this and I think you could use it to great effect in a larger puzzle game.
The wheels move very slowly which forces the player to wait long periods of time to get to the next objective. I'd love to see a version of this where players can control the speed of the wheels. Clicking to change the direction of the wheels was confusing at first, but once I understood it, it made sense.
I would be down to play a fuller fleshed out version of this concept. Good work!
