I haven't played this one through, but I think it's an extension of the work they did on "Sourcery", which was an adaptation of the old "choose your own adventure" books to digital. For that one, they kept the book's story structure, added static images, a map, and a dice-rolling mechanic for combat. So the base story mechanic is multiple choice, with some state (inventory, flags, stats) based on the game play. It's kind of between a text adventure and a novel. To me it feels like they're exploring a new portion of the interactive fiction space, and it's interesting to watch where they take it.
