Sure! Here's an example of a game called "Knife Dodger" implemented as a single HTML file using JavaScript. The game is designed for smartphone operation and uses pictograms as requested.
To play the game, save the above code in a `.html` file (e.g., `knife-dodger.html`), and open it in a web browser on your smartphone. You'll see a gun emoji (`
🔫`) that you can move around by touching the screen. Your goal is to dodge the moving knives (`
🔪`) and collect score cards. If a knife touches the gun, it's game over, but if you collect 20 score cards, you win the game. Good luck and have fun playing!
