Sure! Here's an example of a simple game implemented as a single HTML file, using JavaScript, and enclosed in script tags. The game involves counting up numbers in a box, but with the additional twist of multiplying them:
You can copy and save the above code into an HTML file (e.g., `game.html`) and open it in a web browser. The game will start automatically, and you will see a box on the screen containing a number. The number will increase by multiplying it by 2 every second.
Please note that this is a basic example and can be further enhanced with additional features, user interactions, styling, and more.
