One-shotting a Raccoon Heist game using Claude

An experiment used the Claude Fable 5 AI tool, running inside Claude Code for web, to build an entire 3D browser game entirely from a single prompt and two legacy images derived from a 2022 tweet about a fictional raccoon heist game. The experiment relied on GitHub Pages for live testing, instructed Claude to work completely independently without asking design questions, and provided an OpenAI API key so Claude could generate its own textures and title-screen art.

The AI created a fully functional game featuring a raccoon collecting items like donuts and fish while avoiding guards with flashlights, a police cruiser, and a scent-tracking guard dog introduced on night three. The implementation included procedural low-poly characters, a procedural WebAudio jazz soundtrack, touch and keyboard controls, and automated Playwright testing where Claude took and evaluated its own screenshots to fix mobile visibility bugs and sizing issues.

While the technical execution is striking for a one-shot prompt, the final game is considered mediocre and boring from a design perspective. It lacks team mechanics despite the theme, features stagnant waiting periods once items are cleared, and easily beats the player without offering deep engagement, illustrating that fun game design remains a uniquely human skill.
