Some of the 12 adventures are more "scenarios" than they are short adventures that take approx 2 hrs to complete (which is what I was expecting). The underlying ideas are reasonably creative/interesting. 4 stars for content.
Unfortunately, the PDF is wonky, it hangs up a lot (hourglass) and I sometimes have to wait 30+ seconds for it to "catch up" in order to continue scrolling through the document. I also own a pdf of the Book of Lairs from Kobold, which does not present similar problems when scrolling through the document. Perhaps offering a "print friendly" version for download with artwork that is not as high quality would solve this problem(?). 2 stars for technical implementation.
