Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript and enclosed within script tags.
In this example, we have a game board containing two sisters represented by pictograms of female bodybuilders. When you tap on any sister, they will rotate 360 degrees for a second, simulating a punch. The game loop is set to update the game state every second, and you can add custom logic inside the `updateGame` function. You can build upon this structure and add more features, levels, scoring, etc., based on your specific game requirements.
