Description

This game has been created with three main constraints : using an optical reader as a controller, and use only C language to program it, without any external library except the standard library, and least but not last, only use character Emojis as GFX. That means this game will run under a command line terminal, using characters as game objects.

This is a factory game where you have to read bar codes to enable/disable some machines/modules of the production line. The main goal is to manufacture carnival masks and send them via trucks.

This game was performed during the Global Game Jam 2026 event in Cergy - FRANCE. Enjoy !
