This was fantastic! The intuitive gameplay, the creative puzzles, the undo implementation… If we had to find fault, the jumping-over-rocks mechanic required very precise (oft-failed) timing which felt odd and at times frustrating, but I mention that as the tiniest drop of critique in an otherwise stellar entry. The breadth of content is truly impressive - with every proceeding puzzle, we were certain the end had finally been reached - only to be proven wrong! Well done.
