I had fun running two of my test monkeys (a Ranger and a Mage) through there . For improvements I'd suggest maybe a few more rooms to add variety. Also a unique room with a guy selling ammo would be handy =).
Btw, I am working on a new Version of the Hack and Slash mod...
Just want to say that I really enjoy the mod, it's quite different from the MM modules. Imagine my suprise when my first fighter entered the dungeon, and was torn to pieces within a couple of seconds...
For improvements I agree with Rollo, a bit more variety/eyecandy would be nice.
I also encountered a small bug (not fatal, I could continue playing): When starting the module (on expert) the game gave a "toomanymonsterpictureserror" or something like that, it claimed the number of monsterpictures used exceeded the maximum of 200. I could still play, but the fonts in the game were all messed up. other than that I didn't encounter any problems. (didn't complete it yet)
