Here is a simple example of a playable game implemented as a single HTML file using JavaScript:
In this game, the user can click on the game box (represented by the
element with id "game") to increase their score. The score is initially set to 0 and is displayed inside the game box. Every time the user clicks inside the game box, the score is incremented by 1 and the updated score is displayed. This creates a simple interactive game-like experience.
Note: The provided example is a very basic game implementation. In a real-life scenario, you would need to consider more elaborate game mechanics, graphics, levels, etc., depending on the requirements of your game.
