Horrible
I can understand that this is supposed to be a art game, and I have nothing against that. But one of the important things about an art game is that there's still a game. While this game has gameplay, it doesn't work. The jump button only works when it feels like it, and due to that I could not make it past the second stage. Only because of the fact that the jump button only worked 70% of the time, thus making it near impossible to do this.
If you can fix this, it could be a fantastic game, but a game breaking bug like that just completely ruins it.
