Cozy 3D pixel-art coastal game in vanilla HTML and JavaScript

This entire cozy 3D pixel-art game was built with zero asset files and zero game engines Instead of importing heavy packages, the developer had Claude Opus 5.5 code the entire coastal world directly in vanilla HTML and JavaScript Here is the exact developer pipeline: → prompt Claude to code a zero-engine, pure JS isometric world complete with 3D pixel-art assets → build procedural day-to-night lighting cycles, weather systems, and dynamic lighthouse beams → program interactive gameplay loops like moonlight fishing, low-tide exploration, and whale-bone coves → use iterative prompting to expand narrative acts, dialogue portraits, and swimming whale animations When an LLM can script 3D lighting, moving whales, and day-to-night cycles from scratch without a single PNG, your browser window becomes the engine
