The Green Star

A standalone Atomic Age escape room game reimagined from the 1959 Golden Age comic classic Mysteries of Unexplored Worlds.


The Green Star is a tactile, narrative-driven escape room game designed for home printing. Set in a remote 1950s observatory, the game merges the physical manipulation of paper mission files with a browser-based digital telescope interface.


Players act as agents conducting surveillance on a disgraced astronomer whose research into a "Green Star" reveals the cosmic origins of the universe first established in Bromelain's previous series, The Secret of Langton Manor.

Key Features

  • Authentic Golden Age Aesthetic: The game is built using adapted and reimagined artwork from the 1959 comic classic Mysteries of Unexplored Worlds #13, creating a "living graphic novel" experience.
  • Tactile "Print-and-Play" Puzzles: Unlike purely digital games, gameplay requires physical manipulation of mission files, including cutting, folding, and aligning paper components to solve puzzles.
  • Zero-Friction Digital Interface: A 3D browser-based "Bancroft Telescope Control Panel" companion app simulates 1950s technology. No app store installation is required; the interface runs instantly on any modern smartphone, tablet, or PC as a PWA (progressive web app).
  • Standalone Narrative Expansion: While it reveals some of the cosmic origins of The Secret of Langton Manor universe, the game is a self-contained story that requires no prior knowledge of the series.
