A downloadable game for Windows and macOS

Can you crack the code to save the local convent? 

A train driver has fallen mysteriously out of his window, causing the train to hurtle helplessly down the tracks. The signaller working today isn't the sharpest spoon in the shed. The broken radio means that you can hear him - but he can't hear you. As a last resort, you'll have to communicate through semaphore if you want to save the day.

Using each prompt one time only, you must signal the correct message to warn the nuns of the impending doom, or risk a religious catastrophe. 

Will the crash be avoided? Will the nuns dodge out of the way? Can the buffet car be saved? 

Featuring over 25 unique endings, a cohort of friendly nuns, and a great deal of flag waving. 


This game was created for GJL Game Parade Summer 2021. Created in the space of a week, the theme for this game jam was "One Time Use".

The creators of this game all met in one way or the other through the University of Edinburgh, with three of the team having a background in music composition & sound design. 

Duncan Gallagher - Coder; Game designer

Rossano Cariello - Music; Voice of the Signaller

Nick Harbourne - Sound design; Voice of the Narrator

Jem Gursoy  - 3D Models
