Sure! Here's a simple example of a game implemented as a single HTML file using JavaScript:
To play the game, you can open the HTML file on a smartphone or any web browser. The game consists of a single pictogram (in this case, a game controller emoji 🎮). Each time you click on the pictogram, the score will increase, and it will be displayed on the screen. You can customize and add more features to the game as per your requirements.
