Sure! Here's an example of a simple game implemented as a single HTML file with JavaScript, using pictograms for visuals. This game simulates jumping and can be played on a smartphone.
In this game, there is a player represented by a jumping pictogram. The player can jump by touching/clicking the screen, and they land automatically after a set duration. The game starts with an initial jump by calling the `jump()` function.
Feel free to customize the game further by adding more game logic, keeping score, or modifying the visuals as per your requirements.
