I really like the game. The way it plays with the gravity in different "worlds", and the states of the protagonist are really interesting. But, I have to say that I had a problem. I think there is a bug when I jump in determinated places, because the protagonist get into the walls, and walk into them but I can't do anything, so I have to restart the level. MAYBE it's something that I didn't understood and I can use it to my benefit, but I don't think so.
At least, I liked the game. It's interesting and pretty.
