About Exapunks
It trains assembly-style programming with many agents working at once and moving data between machines. It suits programmers who want hard puzzles wrapped in a story.
It is a paid game from Zachtronics, released in 2018 for Windows, macOS and Linux on Steam, GOG and itch.io. It includes side games you unlock by hacking, and a puzzle tool lets people write custom networks in JavaScript.
