Sure! Here's an example of a maze game implemented as a single HTML file, incorporating JavaScript and using pictograms for the user's current position. The maze will get bigger and harder with each level, and the user will need to complete each level before progressing to the next one. Please note that for the sake of simplicity, this game uses arrow keys for movement instead of touch controls.
To play the game, you'll need to save the above code as an HTML file (e.g., `maze_game.html`) and open it in your smartphone's web browser. The game starts automatically, and you can control the player's movement using the arrow keys. Each level becomes progressively harder, and you must complete one level to unlock the next. The pictogram representing the user's current position is a player icon displayed on the maze grid. Enjoy the game!
