It runs pretty slow on my computer, too, and the interface is pretty weird. I don't like how you have to play from the tiny minimap most of the time. They also took out some useful actions like move+shoot, claiming nobody used them. Heresy!
Anyway, the futuristic dungeon idea has been bounced around quite a bit, and I think a few of us even have rough prototypes. I know I do... I've got some graphics and DSB Lua code I could send you if you're interested in doing something with it... I probably never will.
