Haha I was watching youtube videos on how to do sliding tile puzzles while playtesting it. What to do on the well level is poorly communicated that's my bad, if I wasn't being lazy I would've changed the color of each crank's texture.
It's a really good idea to make the color of the dots inside the well match the cranks actually, I might steal that if you don't mind :)
Thanks for playing, I really appreciate the feedback!
