Script

Sure! Here's an example of a game called "Gravity Ball" that you can play on your smartphone. It uses JavaScript and HTML in a single file, enclosed in script tags. The game allows you to control a ball with gravity by dragging it around and changing the gravity to make the ball move. You can copy the code below and save it as an HTML file to play the game:

This game adds a red ball on a gray box (floor) on the screen. You can drag the ball around by clicking and dragging on it. The ball is affected by gravity, and when it collides with the box (floor), it bounces back up. You can also change the gravity by tapping on the screen. Initially, the gravity is set to 1 (normal gravity), and by tapping, you can switch it to 0 (very low gravity). This allows for some fun, slow-motion movements of the ball. Feel free to modify and enhance the code to suit your preferences or add additional features to the game. Enjoy playing "Gravity Ball"!

You can also change the gravity by tapping on the screen. Initially, the gravity is set to 1 (normal gravity), and by tapping, you can switch it to 0 (very low gravity). This allows for some fun, slow-motion movements of the ball.
