Charming! However I couldn't, for the life of me, manage to jump on the third platform after the first printer, so I saw very little of the game.
The camera is somewhat disorienting at first and the fact that I couldn't really perceive depth gave me a hard time (I couldn't see where my character actually was when jumping, maybe a player shadow on the ground would help a lot)
Fullscreen makes it a bit easier, and you get used to the camera after a while though
