Sure! Here's an example of a simple handball game implemented using JavaScript in a single HTML file:

In this game, you control a player's paddle using the arrow keys or the "Up" and "Down" arrow keys on a smartphone. The objective is to prevent the ball from entering your goal while trying to hit it towards the opponent's goal. If the ball enters your goal or any of the goals, it will be reset and the game continues. The game loop continuously updates and redraws the game objects on the canvas. Note: The game is quite basic, and you can further enhance it by adding scoring, sound effects, and additional gameplay features as per your preference.
