Sure, here's a simple game implemented as a single HTML file. It's a game where you have to collect stars using a smartphone operation. The game uses pictograms and has a timer displayed in the top left corner. Save the code into an HTML file and open it in a web browser to play it.
Please note that you need to have "emozi_all/player.png" and "emozi_all/star.png" images in the same directory as the HTML file for the pictograms to work.
