Our take on This Book Is A Dungeon

The defining structure is repeated experimentation: choices lead through different routes, deaths, and endings, making a single run insufficient to see the full narrative.

What is This Book Is A Dungeon?

This dark horror adventure uses Twine-based interactive fiction, pixel art, and light RPG systems.

Players navigate a sprawling labyrinth through branching paths and choices, solve cryptic puzzles, manage inventory, and engage in combat. The game includes dozens of possible deaths and multiple endings, with experimentation required to uncover different outcomes because one playthrough cannot reveal all content. Its subject matter includes auto-cannibalism, demonic seduction, occult rituals, and bloodfeasting worms. The Steam Edition also includes access to a 40,000-word developer diary as a downloadable PDF from the main menu.
