From the README

Castle Defense is a browser tower-defense game built with Three.js. Defend the gate through 15 waves, build and upgrade towers, and choose between three battlefields and three difficulty settings.

Play Castle Defense in your browser — no installation required.

Every push to master runs the build and scheduler checks, builds the game from source, and publishes it to GitHub Pages. A failed check or build prevents deployment, so the previous version stays online.

The deployment workflow publishes only the generated game as index.html.
