Somewhat strange ... and no more than a fleeting idea given some shape.
... ok, perhaps at $ 0.99 you cannot expect too much, so it is not surpising that everything about this adventure is very micro ... except for its file-size of course.
Beside two stat blocks and a micro map you get three almost half pages and one almost full page of text.
Nonetheless the whole lot of it sums up to an astounding 25MB!!! file-size like a full 500-page rule-book.
Perhaps it would have been a good idea to at least automatically reduce file-size with Adobe Acrobat - resulting in a nice 650KB file after barely 10 seconds of work.
To sum it up: Just an average idea given some small shape at a very large size.
