Just wanted to comment that is is such a cool resource. Visually looks great, and perfect for generating interesting dungeons. Very old school, perfect for a dungeon crawl-head like me!
Haha, thank you very much, Bergasa! Really happy you are having fun with it! :)
At the moment I am also working on a Roll 4 Cave/underdark Version, where the focus is more on natural formations that are hard to traverse, hazards like gas and veins you can harvest.
