I like how you spawn in and instinctively know your way around the first level when you see the dots. Then the ghosts. Then the exit. In the second level I wished I'd taken the guide/tutorial. I got the hang of jumping soon enough but I'm not convinced procedurally generating a maze and which platforms decay, when, leads to solvable levels. That's the price of satisfying theme, and is what makes this original.
Good clean mechanics apart from that small frustration. No intrusive instructions or story, it just worked.
