Moonlight & Mayhem (Raccoon Heist by Codex + GPT-5.6 Sol Ultra)

I decided to pose the exact same prompt to Codex Desktop running GPT-5.6 Sol Ultra - the mode where Sol makes aggressive use of sub-agents - to see how it would do.

It produced a much better game! Here's Moonlight & Mayhem - GitHub repository here, including the textures and prompts it generated using gpt-image-2.

 Your browser does not support HTML5 video.

The original GPT-3 generated game description included:

In “Raccoon Heist”, you and your team of thieving raccoons are tasked with pulling off a series of daring heists. From robbing banks to stealing priceless art, no job is too big or too small for your furry crew.

Fable's version had you as a single raccoon running around a back yard collecting coins and fish. GPT-5.6 Sol has you in a museum, rescuing your two other raccoon crewmates in order to stack on top of each other and bust the golden sardine out of its case.

Much more heisty!

There was one catch though: the version produced from the one-shot prompt had a bug where each raccoon had an eyeball that was enlarged to the size of a giant sphere floating over their head!

The main player character racoon is visible with an enormous polygon-based black sphere four times the size of its body overlapping its head, with a white pupil on it.

You can play that version here.

Despite reviewing screenshots during development Codex failed to spot and correct this bug.

I fixed it by prompting:

Why do the raccoons have huge black spheres on them?

And then:

Fix it

Which resulted in this fix.

I shared the full Codex transcript in the repository - I wish Claude Code had the same "copy as Markdown" feature.
