Sure, here's an example of a simple game where a man is chasing you using pictograms and designed for smartphone operation. It is implemented as a single HTML file containing JavaScript enclosed in script tags.
To use this code, save it in an HTML file (e.g., `game.html`) and make sure to have `emozi_all/player.png` and `emozi_all/enemy.png` files in the same directory as the HTML file. These image files can be replaced with pictograms of your choice. When you open the HTML file on a smartphone, you will be able to control the player's movement by tilting the device. The game ends if the enemy catches the player, and you can restart the game by closing and reopening the HTML file.
