Sure, I can provide you with a simple game code that meets your requirements. However, please note that implementing an entire game with 4K graphics, 10 levels, and player model compatibility within a single HTML file is not a feasible task. The code I'll provide will be a basic game template that you can build upon to create your game. Here's an example:
Backrooms Game
This HTML file provides you with a basic structure for the game, and you can add your own game logic, controls, and graphical representations using JavaScript within the `
` tags. Remember that fully implementing the game with advanced graphics, 10 levels, and compatible player models requires a lot more code and assets, so you may need to create separate JavaScript or CSS files to handle those aspects.
