Very good
Great fun and really enjoyable. Fantastic level editor: it's intuitive and easy to use, and I'm a sucker for level editors on any kind of game.
The CC is a lie? Maybe I need to stop editing levels and play the rest of the game...
Also, if you're making a new one, might I suggest a "kill button", 'cause if you get stuck it can be very frustrating having to start the game again, rather than restarting the level.
Try this out - it's a bit weird and it's only possible because of the character's ability to move in the air. There's very little shifting to use on this level... O_0
