Sure! Here's a simple game that you can play on your smartphone, implemented as a single HTML file with JavaScript:
In this game, you need to click on the ball to score points. The ball is represented by a red circle, and the black hole is represented by a black circle. Every time you click on the ball, your score increases, and the ball and black hole positions are randomized. The current score is displayed on the screen.
Feel free to customize the game further as per your requirements and add any additional features or pictograms you'd like.
