A minimal classic Snake game built with plain HTML, CSS, and JavaScript.

The project focuses on the original gameplay loop only:

• grid-based movement
• food spawning
• snake growth
• score tracking
• game over on wall or self collision
• restart support

• HTML
• CSS
• JavaScript ES modules
• Node.js built-in test runner

npm start

Then open http://localhost:3000.

npm test

• index.html — app shell
• src/snake/game.mjs — deterministic core game logic
• src/snake/app.mjs — browser rendering and controls
• src/snake/styles.css — minimal presentation
• scripts/serve.mjs — zero-dependency local static server
• tests/snake.test.mjs — core logic tests

• Arrow keys or WASD to move
• Space to pause or resume
• Restart button to reset the run
• On smaller screens, on-screen directional buttons are available

This project is static and can be deployed anywhere that serves plain files.

Create a Static Space and upload:

• index.html
• src/
• package.json
• README.md

If you host it separately, it can be embedded with a standard iframe.
