Sure! Here's an example of a simple game called "Rolling Ball Adventure" implemented in a single HTML file using JavaScript. It can be played on a smartphone by tapping to avoid the bricks in the way. I've used pictogram-like characters to represent the ball and bricks.
To play the game, simply copy and paste the above code into a new HTML file and open it in a web browser on your smartphone. Tap the screen to make the rolling ball jump and avoid the bricks. If the ball collides with a brick, a game over alert will be displayed.
