As an AI text-based model, I can provide you with a brief example of how to create a simple game using JavaScript and HTML. However, creating a 3D is beyond the scope of a text-based response. Here's a simple example of a game logic that can be implemented using JavaScript in a single HTML file:
This example creates a simple game where the player controls a ball that needs to avoid colliding with obstacles. The player can make the ball jump by pressing the Space key. The game loop continuously updates and draws the player and obstacle, checks for collisions, and increases the score and game speed over time.
Please note that this is just a simplified example to demonstrate game logic using JavaScript and HTML. To create more complex games or implement 3D graphics, it's advisable to use game development frameworks or libraries specifically designed for such purposes.
