Kind of an interesting design and layout but it is not working at all. The game play is a little hectic (not a bad thing) but the lack of consistency in the architecture, texturing and atmosphere really destroys the level. The item placement needs a lot of work and thin walkways never work in a DM level. Bots play the level just fine but do not go for the 100 health about the spike pit.
Best to leave this one alone.
