This was pretty fun! The mechanic feels really fresh and I think it has a lot of potential. I liked the puzzly thinking combined with timing challenges.

My main complaint (like some other commenters here) is that it's quite slow, and on many of the early levels I knew what I had to do but had to wait ~10-15 seconds. But other than that, I think you did a great job, and I only wish there were more mechanics/levels.

If only the theme allowed you to add a speed up button! Maybe if you held the button down, it'd speed up and when you let go it'll ring.  Risk/Reward.  Very original.

Interesting puzzle mechanics. 

Nice game man. There should have been a button to move the clock fast (for levels with long path).

The idea of the game is really nice, I think you can explore more with the concepts and rules that you set, but as a prototype it is a good puzzle! Well done :)
