## Overview

TuxGear is a browser-based arcade racing game. The player starts a race from the menu, drives with the keyboard, collects track items, and tries to finish three laps before time runs out; the game displays the result and race HUD. The README describes the main runtime modules, while the sampled source confirms input handling, state transitions, AI movement, collisions, and rendering-related code. Since game.js is excerpted, the diagram omits uncertain internal call links.

Main entry points: [`game.js`](https://github.com/kionovelletto/tuxgear/blob/main/game.js) (Game Loop), [`index.html`](https://github.com/kionovelletto/tuxgear/blob/main/index.html) (Game Page), [`style.css`](https://github.com/kionovelletto/tuxgear/blob/main/style.css) (Visual Styles)
