Hacked Dungeon is a small One Game a Month entry I made. It is a bit bare, simplistic and most likely bug ridden (also not balanced very well), but it's free, so perhaps try it out. Maybe you'll like it.
The final build of the game. It contains some bugs, but I will not work on it any more, because I will be participating in April's 1GAM challenge and I just don't have the time to do it. Still, it's free, and I'll give out the source code to mostly anyone who asks (it's not pretty).
