Even though there's the novelty of rolling ball-shaped family members through insane obstacle courses, this game has some fantastic backstory and moral to it. Well played, sir. It's one of the best, and one of the most moving games on this site.
I absolutely love how you revisit rooms to see them turned into a much more sinister area, I think it's genius :) The art is inspiring and visually stunning. I also want to get the book now, so well done; future authors need to promote their books in ways like this :)
