Sure! Below is an example of an incremental game implemented as a single HTML file using JavaScript. This game is designed for smartphone operation and uses pictograms as visual elements.
To play this game, you can save the above code into a single HTML file (e.g., `game.html`) and open it in any web browser on your smartphone. The game involves incrementing the score by clicking the "Click Me!" button and purchasing auto clickers to automate the score incrementation. The game elements and score are displayed using HTML and updated dynamically using JavaScript.
Note: This is a simplified example and can be expanded upon to include more features, levels, upgrades, and design improvements based on specific game requirements.
