The base idea is cool, but I feel like the levels don't make use of this limitation enough, The puzzles I played at least didn't, the difficulty was more about finding the solution to the puzzle or execution (like that first level with the huge leap, which I would reduce btw, I don't think the first jump of a game should ask the players to execute it perfectly). But to do that you would need to build bigger levels I think.
I couldn't finish the game because of the falling box in level 3 or 4. It got stuck at an angle and never reached the button below it, blocking the way for my character. You can fix its rotation so it doesn't happen.
