This entry looked fine at a first glance!
I like generators and this promised some fun action until I realized that this dungeon generator plays itself.
Hence I wrote a small script that will run the dungeon for me: https://jsfiddle.net/yerukzsq/
I am not sure whether the damage is common for both player and enemy and is used to escalate the end of the delving, but I implemented it in a way it is added to the dice result for both sides.
As a game it is not very interesting. As a small script it entertained me for a moment.
