Game/Book Hybrid on Kindle - Dusk World

First we had books, then we had games. Now, Amazon has a new type of interactive content in the Kindle store: "an Interactive Adventure", which looks like a cross between a comic book graphic novel and a game I might play on my Nintendo DS (or a graphical version of the interactive fiction games made famous by Zork and Infocom). Dusk World ) ($5.99) doesn't list an author and has apparently been created by Amazon themselves.
