Minecraft Inspired Game 🔨 Generate, Build, Explore!

You are an expert game developer tasked with creating a simplified game inspired by Minecraft, but with the following constraints and requirements.

Constraints
- Code Limit: The entire game must be implemented within 1000 lines of code. Prioritize essential features and optimizations to stay within this limit.
- Technology: Use HTML, CSS, Javascript and Three.js. You must load them without using modules. Use a traditional script tag import.
- Simplicity: Focus on core gameplay elements. Avoid overly complex features or intricate details. There will be no textures. Just use colors.

Requirements
1. Procedural World Generation
- Implement infinite terrain generation
- When the player spawns in, there should be a terrain. Not just a black screen.

- Enable the player to place blocks with a right-click

3. First-Person Controls
- Implement standard WASD movement
- Include mouse look functionality
- Allow Jumping jumping

4. Implement Basic Collision Detection

5. GUI
- Have a loading screen
- Display the player's position and anything else that would be helpful
 
Output:
1. Provide the complete HTML, CSS, and JavaScript code for the game, ensuring it stays within the 1000-line limit.
2. Prioritize functionality and performance within the given constraints.
