Sure, here's an example of a simple game implemented in a single HTML file using JavaScript:

In this game, you control a blue square-shaped player using the arrow keys on a smartphone. The player can jump with the up arrow key, move left with the left arrow key, and move right with the right arrow key. The objective is to avoid colliding with the gray blocks and red circular enemies. The game will display a "Game Over" message if the player collides with an enemy. Please note that this is a basic example and can be further enhanced with additional features, levels, and graphics. But it should give you a starting point to build upon.
