JaimeUGR/EscapeTheLightrooms ? reverse-engineered prompt

Build me a browser based escape room game where the player explores a 3D room, finds clues, and solves a few puzzles to get out.

I want it to feel like a real little WebGL game, with first person movement, click or ray based interaction with objects, locked pointer controls, simple sound effects, on screen messages, and a basic HUD for hints or feedback. Please make the scene and puzzle flow easy to extend, so I can add more rooms and interactions later.

Use the assets and structure in the project if they already exist, and keep the code organized enough that the main game, room setup, puzzles, collisions, camera control, and messaging are separated. If anything is unclear, check the current docs online and make reasonable choices.

Also make sure it runs cleanly in the browser from the main HTML file, and if there are common loading issues, handle them as gracefully as you can.
