🛥️ Claude Opus 5.5 built this superyacht docking game inside Claude Code: a 46 m yacht with twin engines, bow and stern thrusters, gusting crosswinds, and a Mediterranean harbour town generated entirely from code. Reverse into a gap barely wider than the boat. Every bump costs a star. It runs in your browser with three.js. No game engine, no 3D models, zero lines of code written by hand.

🛠️ TOOLS USED
• Claude Code + Claude Opus 5.5 (type /model to switch)
• A Claude Code skill with the game workflow (research → build → test hooks → verify → fix → ship)
• three.js r186 from a CDN (no npm install, no build step)

💬 THE PROMPT (translated)
"Make me a new game. I want a yacht. Research it on the web first."

📚 WHAT YOU'LL LEARN
• How real YouTube and Reddit numbers picked the game
• How a harbour town, lighthouses and breakwaters come from one height function
• How a superyacht hull is lofted from cross-sections
• Twin-engine and thruster physics: why a yacht slides but doesn't steer sideways
• How Claude wrote an autopilot to dock every berth, and the bugs it caught from the logs

🎮 CONTROLS
↑ / ↓ throttle · ← / → twist (engines split) · Z / X thrusters · Space neutral · C camera · R restart
