The movement is great and creative, and the art and music is amazing, but the game made me very frustrated, as it's much too hard to gauge how high your jump will actually go, which wouldn't be much of a problem in itself if it wasn't for the lack of checkpoints and the comedically long transitions; games like these need almost instant transitions.
Overall, a really great job on this, just missing a few quality of life stuff. Again, I really enjoyed everything about the game, just needs some polish.
