Sure, here is a simple game implemented as a single HTML file using JavaScript and enclosed in script tags. The game can be played on a smartphone and uses pictograms as visuals. Please note that this is a basic example, and you can expand it further based on your requirements.
To play the game, you can replace the `emozi_all/play.png` URLs in the `images` array with actual URLs of your pictogram images. When you open this HTML file on a smartphone, the game canvas will display random pictograms every 2 seconds. Each pictogram will appear at a random position within the canvas. You can further enhance the game logic with scoring, user input, or other features based on your requirements.
