UstymUkhman/WebDOOM ? reverse-engineered prompt

Build me a browser version of classic DOOM using the original game code compiled to WebAssembly, so I can open it in the browser and play it like the real game.

I want the project to support both DOOM and DOOM II, with the same feel as the originals, including the music and sound effects if the files are available. If sound assets are missing, make sure it still works in a no sound mode instead of breaking.

Please keep it simple to run, with a build script that produces the web version in a public folder I can open locally or host online. If anything in the build or asset setup is outdated, please check the current docs online and make the setup as smooth as possible.

Also make the page feel like a proper game launch, not just a blank screen, and include whatever basic browser controls or instructions a player would need to start playing right away.
