It's fine. Struggles with the same problem a lot of platformers do where all the cool ideas are dwarfed both in time spent and mental real estate by the silly precise stuff.

I really don't like the last level though; I hate how it makes a big deal of the rules being broken, but then you still have to continue following the first rule (but none of the others). It's also the first rule the player would be given the opportunity to break, but then if the player tries to, they might infer that the rule book being shattered was a metaphor of some sort and continue playing with all of the game's restrictions (I made this assumption, but luckily tried moving left out of curiosity a couple attempts in).

I probably like this about as much as This is the Only Level (which flirts with some of the same design ideas), but only because of the music and art direction, I think the game design here is worse.
