Description

A browser-based first-person shooter featuring runtime-generated textures, synthesized audio, and enemy AI pathfinding, all contained within a single 290 KB HTML file. The project highlights extreme optimization with no assets on disk beyond Three.js, and was built by an AI agent using five recorded prompts.
