I'm running a game called Abstract Dungeon at Gary Con this year. It something that my company, Sneak Attack Press, is still in the process of developing. However if anybody is interested in taking a peek at the rules before the Con, or playing a session outside of the Con, the beta-test version of the rules are available at our website.
Oh and by the way. The Broken Tower has a wand of wonder in it, and there's still four slots available!
