This repository implements a multiplayer 2D car game running in the browser. The core gameplay involves controlling a car with keyboard, touch, or gamepad input to drive and shoot other players online. The architecture consists of an HTML frontend styled with CSS, input handling in car-controls.js, and game logic/physics/rendering/networking in car.js. Key features include real-time multiplayer via Socket.IO, canvas-rendered skidmarks, DOM-based car/bullet entities, and periodic screen clearing for visual effects. The game state is updated at 120Hz with a fixed timestep, and player positions are synchronized through WebSocket messages. External dependencies are limited to the Socket.IO client loaded from a CDN.
