It's an interesting sort of idea, and I was curious enough to at least try for all the badges. The music was repetitive, but it was calm enough to not mind it too much. Still, a mute button is always welcome. It's not that bad, but could definately stand for improvements. I would actually like to see a full series of these with vampires, mummies, or whatever other mythical creature you can think of. Might be fun to see.
