1. Introduction

How to Install

1. Download the Game Files
   Ensure you have all the necessary files:
   • index.html: The main file to launch the game.
   • style.css: Stylesheet for game design.
   • game.js: JavaScript file for game logic.
   • Supporting assets: Images (e.g., pollution background, monster) and sound files (e.g., correct.mp3, wrong.mp3).
2. Set Up the Files
   Place all the files in a single folder on your computer to ensure proper linking between assets.
3. Install a Local Server (Optional)
   For better performance and testing JavaScript functionalities, use a local server:
   • Using Python:
     • Open a terminal or command prompt.
     • Navigate to the folder containing the game files.
     • Run: python -m http.server (Python 3) or python -m SimpleHTTPServer (Python 2).
     • Open a browser and navigate to http://localhost:8000.
   • Using Visual Studio Code:
     • Install the “Live Server” extension.
     • Open the folder in VS Code.
     • Right-click index.html and select “Open with Live Server.”
4. Browser Compatibility
   Use a modern web browser (Google Chrome, Firefox, Microsoft Edge) for the best experience. Ensure JavaScript is enabled in your browser.

How to Use

1. Start the Game
   • Open the index.html file in your web browser (double-click if running locally without a server).
