Sure! Here's a simplified example of a 3D maze game implemented as a single HTML file using JavaScript. Please note that it is a basic implementation and can be further enhanced with additional features and graphics.
To play the game:
1. Copy the entire code into a new HTML file (e.g., `3d_maze_game.html`).
2. Open the file in a web browser (on a smartphone or computer).
3. Use the arrow keys to navigate through the maze.
4. Reach the red square (exit) to win the game.
