Really enjoyed how this one plays out and moves on from a pretty standard door & switch puzzler. I think it's just about the right length, the hook doesn't get stale before the game ends, though I do think there's some visually ambiguous parts (it can be hard to tell how the doors will behave in response to the switches). The difficulty is also pretty low, which is mostly a good thing, but a harder level or two to cap off the experience would be great.
