The Long Silence is a procedural 3D space-exploration game that runs in a browser tab, built entirely by Claude Opus 5. No pre-made assets — every star, planet, ring system, and nebula is generated from a seed and rendered in WebGL2, with atmospheric scattering, auto-exposure, and a hand-built flight model. The game has a narrative: 40,000 years ago, 900 inhabited worlds fell silent in four days — and you fly a survey vessel to find out why.

Why a vibe-coder should care

This repository is a concrete reference point for what an AI agent can build today. If Claude Opus 5 can create a complete playable game with complex rendering and flight physics, the scope of what you can delegate to an agent is larger than most people assume.
