Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript. The game is called "Argus Sniper" and it can be played on a smartphone. It utilizes pictograms for a visual representation.
In this example, the game "Argus Sniper" starts when the page is loaded. It sets up a canvas element on which the game elements are rendered. Two pictograms are displayed on the canvas, and the player can click on them to increase their score. The game lasts for 30 seconds, and the score and timer are updated and displayed in real-time.
Please note that you'll need to replace the `emozi_rabbit.png` and `emozi_apple.png` with the actual paths to your pictogram images.
Feel free to customize and enhance the game as per your requirements!
