dirien/backrooms ? reverse-engineered prompt

Build me a browser based horror game that feels like the Backrooms, with a playable 3D world in the browser and a creepy, lonely atmosphere.

I want two selectable levels, The Lobby and Terror Hotel, each with its own look, audio, and layout. The player should wake up in a maze like place, explore in first person, find ringing phones, and connect three different phone lines to escape. Add sanity, stamina, a flashlight that can run out and recharge, sprinting, mouse look, keyboard movement, touch controls for mobile, and a pause menu with settings that save locally. Make the rooms stream in as the player moves, so the world feels endless, and keep the lighting, sounds, and enemy encounters tied to the sanity level.

Please make it polished and playable, with a simple HUD, subtitles, restart flow, and enough guidance so the player can understand what to do without breaking the mood. If you need to check current docs or best practices for Three.js or Vite, look them up online first.
