Sure, here's an example of a text-based maze game implemented as a single HTML file using JavaScript. Please note that this is a simplified version and does not include pictograms or smartphone-specific optimizations.
To play the game, run the above HTML code in a web browser. The maze layout is represented using ASCII characters: 'S' for the starting point, '#' for walls, 'G' for the goal, and empty spaces for the paths. Use the arrow keys on a keyboard or arrow buttons on a smartphone to control the monkey and navigate through the maze. The goal is to reach the 'G' character to escape the maze.
