The full story
Cozy Cafe is a relaxing idle clicker game: serve coffee, hire baristas, unlock upgrades and grow a café franchise, with a prestige reset for permanent multipliers. It was built with Claude Code (Opus 4.5) in plain HTML, CSS and JavaScript, using the Web Audio API for sound and local storage for saves. The author notes that balancing exponential growth was the tricky part.
