Do you have some specific doubts about the design or is this based purely on the lack of good looking examples?

Anyway they plan to back a few showcase games so they are headed in that direction, this is one of them:

I'm not so deterred by the lack of examples but I do have doubts about the design and how complex it seems. Maybe that pays off with bigger projects, we shall see.
