This is an excellent introduction to Shadowdark and level 0 gaunlets. I ran this for my first time DMing Shadowdark, and all my players were new to the system as well.
My players instantly embraced the lethality and dark comedy of the situation they had been thrust into. By the end they were chanting the incantations of the slime lord in unison whenever anything noteworthy happened. They escaped the dungeon with many tales of sacrifice and glory. Highly recommended.
