[feason]

Description

• Implements a classic Snake game with HTML, CSS, and JavaScript.
• Code Changes:
  • index.html: Defines the game structure, including the canvas, score display, speed selector, pause/game over overlay, and mobile-friendly directional controls.
  • styles.css: Provides the visual styling for the game, HUD, overlay, and controls.
  • script.js: Contains the core game logic, including snake movement, food generation, collision detection, scoring, high score persistence (using local storage), game state management (running, paused, game over), and input handling for keyboard (WASD/arrow keys, Space for pause, R for restart) and on-screen D-pad.
