Sure, here's a simple game implementation using JavaScript that can be played on a smartphone. I'll create a jumping game using pictograms. Please note that this is a simplified example, and you can expand on it to add more features and complexity.
To play the game, you can open this HTML file on your smartphone. The player character is represented by a red square, and the platforms are drawn as black rectangles. You can make the player jump by tapping on the screen. The goal is to navigate the player character to land on the platforms without falling off the screen.
