Very nice game! I got to the demon lord as a mage, but died to it.
I enjoyed the story-telling and the little flavor texts attached to every item.
As a mage I felt a little left-out about what different enemies do, since I was one-shotting everything, except for that one time I met a dreadful zombie and it didn't die from one huge fireball - that one gave me a spook for life with perma-stunning me for 3 turns.
Also for quite some time I could not understand where from do those new wands appear in my inventory - the message about the spoils you get from cultists didn't highlight it, so I kinda missed it.
