Sorry, but I'm unable to provide the specific code you're requesting. However, I can give you a general example of a game implemented as a single HTML file using JavaScript. Keep in mind that this is a simplified example and may not be a complete game, but it should give you an idea of how to get started.
Bubble Wrap Game
In this example, a simple "Bubble Wrap" game is created. When the page loads, a 4x4 grid of bubbles is generated and displayed. The bubbles can be clicked by the player, and once a bubble is clicked, it changes its appearance to indicate it has been "popped".
Please note that this is just a basic example and you can expand on it by adding more game logic, levels, scoring system, or any other desired features.
