Interesting idea, I played it a few times. First I did not understand why the gears were popping out. The sizes where correct and it did start turning the machine with score going up. But then it just popped out one random gear. I was trying to move each part so that it fits with the teeth perfectly, but always one of them popped out. But then I realized that I can just quickly pop it back no mather what angle and continuing to turn the handle, so I could finish the level :))) Sweet idea, good job!:) I tried as well your other game, the Sound Spiner, really nice play with sounds!! Relaxing :))
