It's a cool and quite interesting concept for a regrettably underused theme and I appreciate the work that went in. The review by Lukas K. gives a good impression and I agree with most of it.

HOWEVER: This product is in dire need of an editor and some polish. I don't mind the Office Document look all that much and like that there are is least some fitting art, but the least I expect when I pay money for something written is proper and consistent formatting and spelling. It's not terrible, but it could be quite a bit better.
