Script

Sure! Here's an example of a simple game implemented as a single HTML file with JavaScript. The game uses a joystick-like interface to move an avatar left and right on the screen. Please note that this is just a basic demonstration and can be expanded upon for a full-fledged game.

This game creates a canvas element where an avatar is displayed as a blue square. The joystick control is represented by a light gray circle. By touching the left side of the joystick, the avatar moves to the left, and by touching the right side, the avatar moves to the right. The game continuously updates the avatar's position based on the joystick control. You can save this code as an HTML file and open it in a web browser on your smartphone to play the game.
