This is the game I have been waiting for! Since the days of "Escape from Dragon Mountain" I had hoped for someone picking up that work.
Very nice!!!
Please don't forget to include:
* Doors can kill Monsters
* No Music, just atmosphere!
* the real dungeon crawler mind maps the dungeon
* don't fireball against the wall
I am totally happy with tile based movement!
One argument in favour of looting items separately: "Take all" option minimizes the surprise moment when finding a magic weapon underneath the pile.

Please include a Linux version! I think your game could be very successful if you distribute it via Ubuntu Software Center/Ubuntu One. If the game is reasonably priced, this community will most certainly support you
