I really like this original interpretation of the theme, cool idea!
Unfortunately, I think the game is really quite difficult (on all difficulty settings) due to the speed at which the cranks unwind. Getting the platform from the bottom to the top takes a really long time and it's difficult to do. I also miss-click often, as I have to keep shifting my attention between looking at the ball and looking at my mouse to click the cranks.
I think a good way to solve this problem, would be to bind the activation of the cranks to keys on the keyboard. That way, you can keep your focus on the ball and platforms and you can also rewind all the cranks at once by holding all the buttons at once.
I'd really appreciate it if you would have a look at my game as well, and be sure to download the smaller version :D
