Turbo Kart Rush

Turbo Kart Rush

**An arcade kart racer in the spirit of Mario Kart, built entirely with Three.js. Every mesh, texture, sound effect and music track is generated in code at load time. There are no asset files in this repository.**

The whole game was produced by five Claude Fable 5.1 sub-agents working in parallel from a single prompt, without a single follow-up question. The prompt is reproduced below.

Open **https://bridge-mind.github.io/turbo-kart-rush/** in a desktop browser with WebGL2 (Chrome, Edge, Firefox or Safari). Click or press Enter on the title screen, choose one of eight racers, pick a circuit and difficulty, then Start Race. A keyboard or a gamepad works.

Three laps against seven AI drivers. Drift through corners and release for a mini-turbo. Grab item boxes and fire shells, drop bananas, pop mushrooms, or call down lightning on the field.

The prompt that built this

This is the complete, verbatim prompt given to Claude Code. Nothing else was specified.

I need you to launch five Fable 5.1 sub-agents and help me build a triple A quality game that is a clone of Mario Kart. What I want you to do is I want you to launch these sub-agents, build the game without asking me any questions at all, and use 3JS to build the game. And once you're done, report back to me.

How it was built

The orchestrating agent wrote an architecture contract first, then launched five sub-agents that each owned one slice of the codebase and built against shared TypeScript interfaces and a typed event bus. No sub-agent edited another's files.
