About This Book Is A Dungeon

✦ AI summary

Navigate a nightmarish Twine-based dungeon crawling with cosmic horror, gruesome puzzles, and dozens of ways to meet a grisly end as you chase multiple endings through an interconnected narrative labyrinth. Blending interactive fiction with pixel art aesthetics and light RPG mechanics, this is an unapologetically dark experience designed to reward bold experimentation and repeated playthroughs that reveal new paths and twisted secrets.

Auto-cannibalism. Demonic Seduction. Occult Rituals. Bloodfeasting Worms. This Book Is A Dungeon has it all and more. This dark, horrific Twine-based dungeon crawler pairs edgy interactive fiction with grisly pixel art and light RPG elements. Prepare to be disturbed, titillated, and savaged by unholy denizens aplenty in your quest to navigate this sprawling narrative-driven labyrinth bristling with otherworldly doom.

WARNING: THIS GAME WILL KILL YOU. OFTEN.

  • Solve cryptic and disturbing puzzles
  • Die in dozens of horrible ways
  • Enjoy light RPG elements, including combat and inventory

This game is not for the squeamish or faint of heart.

BONUS GAME DEV DIARY EBOOK



This Book Is A Dungeon was originally created as an interactive fiction and self-publishing experiment. It was initially launched as a game inside a Kindle book that served as a developer diary documenting the entire process for creating the game from start to finish. As part of the Steam Edition, you can access a free download link for a PDF version of the dev diary within the main menu.

This Book Is A Dungeon takes the familiar idea of a dungeon crawler and transforms it into something closer to a sinister interactive novel. Instead of navigating detailed 3D corridors or fighting enemies through real-time combat, the player advances primarily by reading descriptions, making choices, examining disturbing situations, and accepting the consequences of curiosity. Developed by Nathan Meunier and published by Plug In Digital, it is a deliberately unconventional horror experience built around interactive fiction, light role-playing mechanics, puzzles, and repeated experimentation. Its minimalist presentation may initially appear simple, but beneath it is an adventure that takes considerable pleasure in making exploration dangerous. The dungeon functions as a branching collection of encounters where seemingly ordinary decisions can produce dramatically different outcomes. Players investigate rooms, interact with questionable objects, encounter grotesque creatures, and decide whether potentially dangerous opportunities are worth pursuing. The game frequently rewards curiosity with useful information or progress, but it can just as easily respond with an unpleasant death. …

The game turns into a trial-and-error clickathon that forces you to keep repeating the same actions dozens of times to get back to the point where you get to guess which option to choose next to proceed. Would be ok as a free game, as this is clearly someone's first attempt at making a game.
