Sure! Here's a simple game implemented as a single HTML file that uses JavaScript and can be played on a smartphone using pictograms.
Please note that you need to replace "emozi_all/cat.png" and "emozi_all/dog.png" with the actual path to your pictogram images. Also, you can uncomment the lines for a background image if you have one. Feel free to add more game elements and logic to suit your game idea.
