As indicated in this screenshot, This Book is a Dungeon is a) a Kindle book about game development with Twine and b) the Twine-based dungeon developed as described in the book. The word “Bookumentary” makes my teeth itch a little, so I will pretend I didn’t see that. And I can’t comment on the success of this piece as a self-publishing experiment, so I’ll just talk about the first two aspects.
The book is 81 pages long, which means that the book and game together are definitely far outside the usual “I will play this in 20 minutes in my lunch break” realm occupied by most Twine pieces — though it’s written in a breezy, confident, slightly repetitive style that makes it a pretty fast read:
It’s truly rare to find me doing only ONE thing at a time. Ever. I’ll admit that my rampant ADD is partly to blame. I try to work this incessant need for chaos and spinning plate juggling to my advantage, though it sometimes bites me in the ass. I can’t ignore this one, though. The drive is too great. Plus it’s new and shiny, so off we go!
