Alone in the Dungeon is a hack of Takuma Okada's Alone Among the Stars. In it, you are a Dungeon Delver, a solitary individual who ventures into the depths below the surface seeking treasure.
A standard deck of 52 cards and a six-sided die are used for your explorations. You can make a journal of what you find along the way. If you want, you can keep the journal, but you don't have to.
Find it here.
