Tone Zone Survivors

Problem

The README sets a deliberately small brief: a Vampire Survivors-like in plain HTML5 canvas, with no build step, where you open index.html and play.

What it does

• Move with WASD or arrow keys, or drag on touch screens.
• Weapons fire automatically.
• Pick an upgrade on level-up with keys 1-3 or by tapping.

How it is built

• Plain HTML5 canvas; the game code lives in src/game.js and src/sprites.js and is loaded from index.html.
• A smoke test (tests/smoke.js) runs with Node.
• Cloudflare deploys every push to main through its GitHub connection; npm run build copies the game into dist/ and wrangler deploy publishes it (config in wrangler.jsonc).
• The repo carries agent rules (CLAUDE.md), a plan (ROADMAP.md) and a living log (MEMORY.md) so agent sessions can pick up where the last one stopped.

What is interesting

• No framework and no bundler: opening index.html is enough to run it.
• It is developed with agent sessions, guided by in-repo rules, roadmap and memory files.
