Sure, here's a simple game called "PictoFire" implemented as a single HTML file playing on smartphone:
In this game, you need to click on the fire pictogram to put out the fire and earn points. The fire pictogram will move randomly on the canvas, and you need to keep track of your score. The game will start when you click on the canvas, and you can restart it by refreshing the page.
Please note that you need to replace `"emozi_rabbit.png"` and `"emozi_all/fire.png"` with actual image files for the fireman and fire icons respectively.
