Good job on the rope physics, they must have been a pain to get to work correctly!
Very interesting concept, unfortunately it didn't really give me any "Aha!" moment that you hope from a puzzle game. I was mostly just plugging things vaguely where I thought they'd be high enough. Maybe some of the later puzzles would have given me that feeling, I didn't fully beat the game.
One small note on the jump controls: you need to hold the button to keep rising but as soon as you touch the ground again that causes the character to jump again. It would be better (I think) if they'd only jump OnButtonJustPressed
