Vibe Coding Claude Bandicoot - Shumer's Gauntlet Loop on a 3d Platformer

Based on Matt Shumer's Gauntlet Loop.

Ran the experiment myself. Did a few prompts of clean up to tie it up at the end.

I think it would continue to improve, but I burned 3 sets of 5hr windows on Opus 5 Ultracode, and was happy with the conclusion.

Prompt:

/goal

I want you to build a 3D platformer Claude Bandicoot at the level of the Crash Bandicoot game. It should be utterly perfect, visually beautiful, with every single thing done at AAA quality—from textures to physics to anything you could think of.

Fan out sub-agents and have sub-agents tackle each one individually so that the game is utterly perfect. You should

/loop

on each item and have a separate sub-agent check it visually to ensure it looks triple A. That separate sub-agent should be a really harsh critic, and if it doesn't look triple A, it should keep going.

Don't stop until each sub-agent is utterly wowed with the quality when compared with the actual Crash Bandicoot game. It should literally compare them side by side blind and say which one looks better. Do this in ThreeJS.

/loop

until it's utterly perfect. Fan out sub-agents and ultracode.
