About This Book Is A Dungeon
This Book Is A Dungeon is a Twine-based dungeon crawler that combines interactive fiction, grisly pixel art and light RPG elements. You navigate a sprawling labyrinth in a grim, story-driven horror adventure featuring demonic denizens, occult rituals, auto-cannibalism and bloodfeasting worms.
Choices and endings
You experiment with different paths and choices to discover where they lead. The game’s content cannot all be experienced in a single run, and your choices can lead to dozens of ways to die and multiple endings.
Puzzles and combat
The labyrinth contains cryptic, disturbing puzzles. Light RPG elements include combat and an inventory.
Developer diary
The game also includes a 40,000-word developer diary. It documents the process of creating the game and was originally part of an interactive fiction and self-publishing experiment. In the Steam Edition, a PDF version is available to download from the main menu.
