What it is
A Snake game that teaches cyber security concepts as you play, co-built as the CyberDefender workshop for Decode 4.0. Arrow keys, browser, no install, no signup.
Why a game
The workshop format it replaced was a slide deck. Attendance at a voluntary security session depends on whether the first thirty seconds are interesting, and a playable thing clears that bar in a way a deck does not.
42 forks, which for a workshop artefact is the useful signal. People took it away and ran it themselves.
Stack
TypeScript and Vite, rendering to canvas. Deliberately small, so a student can read the source in one sitting and modify it during the session.
