Excellent idea, cool take on the puzzle platformer/adventure game concept! The princess level is difficult and seems very "moon-logic". The goal is clear, but it's unclear how the tools given help you achieve it, unlike the levels preceding.
One issue i'm seeing with the them in general is that it's hard to "rewind" a game w/o it just feeling like hitting "retry" on a puzzle or doing yet another time-reversal based game. This is NOT a knock against this game in anyway, more against the theme itself. This is one of the best games of the jam and the best one I've played so far!
