A well put-together puzzle platformer. The most notable flaw is the difficulty curve - there are a few too many tutorials at the beginning, and after that point it feels like the difficulty is pretty inconsistent. I never felt like I didn't immediately understand what the level's solution would be, but that is reasonable given the game's length.
This is a well made, short game experiment that executes on its premise. The platformer movement is satisfying to control and the main mechanic is well realised. It'd be interesting to see how far it could be pushed as an expanded release.
