I really enjoyed this experience, and was impressed by the execution and polish. It was fun to solve the factory style puzzles, and the "Last Clockwinder" mechanic was fun to play around with. Your skill and effort shine here.
I'm not sure you actually need the clockwinder stuff, though. I had a good amount of fun just solving the puzzles. I could imagine a version of this that you could play in an immersive first person way, then zoom back and play in a more traditional way.
I would have been helpful to have some kind of indication of how many avatars were available to me. If it was there, I missed it.
These are small critiques though. Really excellent work.
