Sure! Here's an example of a simple game where you play as a doctor and need to dodge heart break emojis to keep the patient alive. The game will be playable on a smartphone and use pictograms.
To play the game, copy the above code into a blank HTML file (e.g., `game.html`) and open it in a web browser on your smartphone. You'll see a doctor emoji at the bottom of the screen which you can move horizontally by touching and dragging. Heart break emojis will start falling from the top, and your goal is to dodge them by moving the doctor emoji. If a heart break emoji touches the doctor, the game ends, and your score will be shown in an alert dialog. Keep avoiding them as long as possible to achieve a high score. Good luck playing!
