Best on a computer

An anti-gravity racer in the style of the PS2 era: you fly low over neon tracks through a night city, trimming your nose to dive for speed or lift for grip, and drifting through the corners. There is a career that starts with easy races, single races against seven AI pilots, time trials against your best run's ghost and a training section for the controls. Up to eight people can also race each other online or in one room, each on their own device. The music comes from a generator built into the game.

How the creator made it

The creator made the game with Claude, almost entirely in its phone chat app: they say they started with a 17 KB prototype and reached this game 50 versions later. They say most of the work went into the frameworks that keep the generated music coherent, and the game is “just claude 3js code”.

Code
In the creator’s words: “honestly this is just claude 3js code”, and “I've done this all in chat.” They say the core gameplay is 17 KB, and the rest of the 40 MB is tweaks and “honestly mostly the music generator”. ↗
Art
Claude first made “really blocky models”; after someone said they looked like a single prompt, the creator spent “an hour of talking to claude to get the models to look better”. ↗
Sound and music
The creator says they went down “a rabbit hole of building a procedural reactive multi genre music generator”, and that “The majority of the work was in providing the frameworks that keep the music coherent.” ↗

If you want to try something like it

  • Ask the AI how to talk to it: the creator says “the best way to do this stuff is to ask it to tell you how to talk to it.”
  • Have other AIs review the work: the creator suggests getting “other llms to review claudes work”.
