Built this with Claude Code Opus 4.5. It's an idle/clicker game where you run a coffee shop.
Tech: Pure HTML/CSS/JS, Web Audio API for sounds, localStorage for persistence, Stripe for payments.
The interesting parts:
- Balancing exponential growth is tricky. Used cost multipliers (1.4x-1.8x per upgrade level)
- Web Audio API can generate satisfying sounds with just oscillators
- Prestige systems add surprising depth to simple mechanics
I asked Claude to just do this pretty simple - about 1200 lines of JS total.
Happy to chat about this new way of "we can just build it"
