Hi, yeah, that's me. I took it down a while back, but could be convinced to post it again.

Yeah, I've mostly run it with John Harper's 2-page World of Dungeons, but that does leave a lot of the creative & mechanical lift up to the GM, more than I would normally prefer in a player-focused game. I've always had visions of making a bespoke system for it , but that won't likely happen anytime soon. I'll see if I can dig up the original InDesign files or at least an openable PDF.
