Sure! Here's a simple game implemented as a single HTML file using JavaScript. It requires the user to press a jump button to make a ball jump up and then fall back down using gravity. It's designed to work on smartphones and uses pictograms to represent the ball. Here's the code:

🏀

Jump

To play the game, simply open the HTML file in a web browser on your smartphone. You'll see a ball and a "Jump" button on the screen. Press the "Jump" button to make the ball jump up and then fall back down to the floor using gravity. Note: Since I can't directly execute JavaScript here, you'll need to copy and save the above code in an HTML file and test it in your browser.
