To play the game, follow these steps: 1. Copy the entire code. 2. Paste it into a new file with a `.html` extension (e.g., `game.html`). 3. Save the file. 4. Open the saved HTML file in a web browser. 5. Interact with the simulated command prompt by typing commands and pressing Enter. Please note that this is a simple simulation and not a full-fledged game. It allows you to enter DOS commands and simulate a basic interaction with a Windows OS through the command prompt.
