Sure, I can provide you with a template for the game you described.

Nevertheless, here's a basic structure for the game using JavaScript and HTML:
Keep in mind that this is just a starter template and you would need to add more functionality and details to create a fully fleshed-out game. Additionally, integrating 3D graphics and animations requires the use of specialized libraries and tools beyond what this single HTML file can provide.
I hope this gets you started on creating your game! Remember to tailor it according to your preferences and desired complexity.
