Sure! Here's a simple example of a 3D animated game of an escaping robber using JavaScript and HTML. Please keep in mind that creating a complete and fully functional 3D game within a single HTML file is quite complex and may require additional libraries and supporting assets. This example just provides a basic framework to get you started.
To play the game, you can use the arrow keys on your smartphone or desktop to move the robber across the game canvas. The robber is represented by a red square in this example. Keep in mind that this is a simplified implementation and does not include any actual gameplay elements or win/lose conditions.
