Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript. The game is called "Pictogram Match". It can be played on a smartphone and features pictograms. Feel free to use and modify it to create your own game.
Pictogram Match
Score: 0
To use this game, you'll need to prepare the pictograms as image files (e.g., `emozi_all/game.png`, `emozi_all/pictogram.png`, `emozi_all/pictogram.png`) and place them in the same directory as the HTML file. You can replace these pictograms with your own as needed.
