A really interesting concept! Most of the levels are designed so cleverly that I genuinely have no idea how the developer managed to put them together. Everything feels carefully planned down to the smallest detail, and I couldn't find any way to break the intended sequence.
The game is difficult, but it always feels fair and understandable. After a couple of attempts, you usually figure out what the game expects from you, so you never have to play that frustrating game of “guess what the developer was thinking.”
