Escape for mamanar

Convert my complete "Love Escape" 3D mobile escape game into ONE SINGLE HTML FILE.

IMPORTANT REQUIREMENTS:

Output only one complete HTML file. Put all CSS inside <style>. Put all JavaScript inside <script>. Do not create separate CSS or JS files. Do not use npm, build tools, or external installation. The game must run directly in ArcadeLab by pasting the HTML. Use Three.js for 3D graphics if supported; otherwise create a lightweight pseudo-3D game using Canvas. Make sure the game actually works, not just a demo screen. Use mobile landscape orientation and responsive touch controls. No missing functions, undefined variables, or broken buttons. 

GAME: LOVE ESCAPE

Create a playable 3D escape game:

Boy starts on floor 1. Girl starts on floor 3. Three-floor house with rooms, walls, doors, furniture, and stairs. Characters can move separately using a character-switch button. Walls and furniture block movement. Guards patrol and chase visible players. Collect hidden number notes. Enter the secret code using the main door keypad. Both characters must reach the exit to win. Ghost power makes the player invisible for 60 seconds, once per level. Sprint with cooldown. Game over when a guard catches the player. Add Easy, Hard, and Extreme modes. Implement levels 1–3 fully playable. Add level selection for 15 levels. Coins, stars, shop, outfits, and local save using localStorage. Add start menu, pause menu, game over screen, and victory screen. Add sound effects using Web Audio API. Extreme mode has darkness, a 3-minute timer, and alarm. Make the game playable with touchscreen joystick and buttons. Also support keyboard controls: WASD and arrow keys. 

TECHNICAL:

Return the entire HTML document starting with . Include all code in one file. No explanations before or after the code. Ensure every button works. Test and fix JavaScript errors. Optimize for low-end mobile phones. Make a complete playable first version, not just a concept.
