Very nice idea for the mechanic, I really enjoyed playing it! I finished the game but did not manage to fully max it out with collecting all clocks (unless it was sometimes impossible, but I assume Green mark is for "fully cleared" and blue for just finished). The music really fit the speed and rewind vibe of the game <3 And the rewind mechanic itself was very satisfying to watch and use. I would play around more with that rewind, like going somewhere to push a button that unlocks another passage etc. etc.
