Sure, here's an example of a simple dodging game implemented as a single HTML file, containing JavaScript code enclosed in script tags:
To play the game, save this code into a file with the extension ".html" (e.g., `dodging_game.html`), and open it in a web browser that supports JavaScript. The game can be played by moving the mouse to control the blue player square and dodging the green circles. If a green circle stops moving, it means it will move really fast when it continues. The game will end when the player collides with a circle, and the final score will be displayed.
