The game looks and sounds great! The concept is charming as well but the tutorial is pretty harsh. Dying at all sets you all the way to the beginning so you have to redo portions of the game that have already been covered. This also happens a lot because the platforming is pretty tight. You also can't move on quickly even if you know what you're doing because your stages are intertwined with movement, so stopping is required in order to properly advance.
Essentially, the idea and execution are stellar. The pacing early on can be grueling though, which is a shame because the game as a whole is great.
