The game's source code is public and can be found on GitHub. Alongside the source, pre-built releases can be downloaded.

Realized for the 1bitjam, a gamedev jam organized by the italian community GameMaker Italia. The jam title partially explains the rules: the final render must feature two colors only (hence virtually 1bit of information per pixel).

The game is built using GMS2.3.


You are a teleprinter operator, hired by the army in order to send various messages across the country.

Mistakes will not be tolerated.
