Best on a computer

You drive a rocket car around an enclosed stadium and try to knock an oversized ball into the other goal, using boost pads, jumps, flips, air rolls and wall driving. Matches are 1v1 against a bot or 2v2 with a bot teammate, at Rookie, Pro or All-Star skill, and there is a practice mode with an empty field. Ramming the other car at supersonic speed demolishes it, and a ball cam keeps the ball in view. An online mode lets two players meet with a room code. Best on a computer: it needs a keyboard or a gamepad.

How the creator made it

The creator says Claude Opus 5 produced the initial racer from one prompt, with minor follow-up changes. The repository says the physics use measurements published by the Rocket League community, and the game generates its car mesh, textures and audio at runtime. For online play, the creator added a Cloudflare Worker for the connection and had the room host's browser run the match.
