Anna Anthropy, designer behind Dys4ia and Triad, and author of Rise of the Videogame Zinesters, just released a Halloweeny digital choose your own adventure book. It's really charming—you can go between telling jokes to skeletons to finding a Crystal City. Purchasable here. (Update: full disclosure...Anthropy was housemates with me and a mutual friend in the summer of 2012.)
