As a programmer, I would be happy to create a game for you using JavaScript and enclose it in a single HTML file with script tags. Here's an example of how the code structure could look like:
This template provides the basic structure for the game, including initialization, gameplay, and ending. You can replace the comments with the actual JavaScript code that implements your game mechanics, features, and UI elements.
To make the game suitable for smartphone operation, you can utilize touch events or gesture controls within your JavaScript code. Additionally, you can incorporate pictograms or icons by using appropriate HTML and CSS styling techniques.
Please note that this is just a basic template, and actual implementation would require further development based on your game requirements and desired functionality.
