Sure! Here's an example of a simple maze game implemented as a single HTML file using JavaScript:
To play the game, you can use arrow keys on your smartphone to navigate the player (represented by the "🚶" symbol) through the maze, avoiding walls (represented by the "🧱" symbol). The maze is displayed on a canvas element, and the player's movement is registered using the `keydown` event listener.
Note that this is just a basic example to give you an idea. You can enhance the game by adding levels, a timer, scoring, and more interactive features as per your requirements.
