Dungeon Janitor’s Apprentice is a two player storytelling game. The author writes:
Dungeon Janitor’s Apprentice is a storytelling game for two! One player is the Dungeon Janitor, who wants to get the dungeon cleaned as quickly as possible. The other player is the Dungeon Janitor’s new Apprentice, who wants to get stuck doing as little work as possible. These two characters argue by making up backstory for the dungeon.
To play, you’ll need just some tokens and the rules. You’ll get a double-sided PDF that you can print and fold into a little rules booklet (as well as a plaintext version). On the back of the rules is a labelled dungeon map to help inspire players during play.
