Browser-Based Rocket League-Style Soccer Game

A browser-based 3D Rocket League-style soccer-with-cars game plus a roughly 67-second screen recording of its camera work. Built with Three.js rendering and the Rapier physics engine, it includes a drivable rocket car, boost and jump mechanics, goal detection, scoring and a timer, and a HUD. The author used a long prompt to have Opus 5.5 build it end to end and iterated 8 to 10 times. Useful as a reference for game development demos.
