The concept art is nice, and the little video is pretty well made. Team also seems to have industry experience (although making a game called "my underpants" doesn't necessarily inspire confidence - to be fair thats only one among many, though). We'll see where it goes, it could be interesting, but I'd like to see at least a techdemo or something. I agree it seems a bit early to go KS for this, but it's a good idea for them to start building some interest in the game before they go KS.
So let's watch how this develops.
