Sure! Here's an example of a simple maze game implemented as a single HTML file using JavaScript:
You can copy the entire code and save it as a single HTML file (e.g., `maze.html`). When you run this file in a web browser, you'll see a maze displayed on the screen with a player represented by a monster emoji ("
👾"). Using the arrow keys on your smartphone, you can navigate the player through the maze to reach the goal ("G").
Please note that this is a simplified example and it only represents one level of a potential maze game. You can modify the `maze` array to create different maze configurations or even introduce multiple levels. Additionally, you can customize the styling and the pictograms used in the game to fit your preferences.
