Thank you for the feedback, we couldn't use so many time on polishing the collision and doing more levels to improve the puzzles and giving the rewind more uses, but we have in mind some ideas to make better use of the mechanic in a possible post jam version, and we'll make sure to make the rays more useful in the puzzle half of the game. About the rewind, actually you can move the platforms at your will with your head and the rewind will play that backwards, but we couldn't find a good use for that in time.
