From the developer:
Backworld is a game about the the Rabbit, and some mysterious character with a paintbrush. It seems like there are two sides to everything - the frontworld and the backworld - and by painting the world the mysterious character with the paintbrush can decide what side is reality for the rabbit at what location.
