The knob is quite hard to control at first until I realized that I have to click, drag it to the fullest to get the mouse range before moving it back to unwind (very unintuitive). It took some time to understand the mechanics as I have to go back and forth between the tutorial and the gameplay. I wish there is a retry button instead of waiting for the retries to end just to try again. Interesting puzzle tho, would be great if it is intuitive and easy to understand at first.
