Well... props to you for putting in a discovery thing that's more than a texture on a wall or a loud sound effect. But while I'm aware of the possibility of something going over my head, I can't say I found the "secret" to be all that worthwhile. Wait five hours to hear a 3 minute long WAV file with binary code that translates to some meme-like phrase that turns up vague results in a search engine.

Okay then.

I'll be quite surprised if someone does manage to come across that "legitimately" without just going AFK, since the map's hardly interesting enough to idle around for five hours in.

At the very least, I do like the feel of recreating something from The Beginner's Guide. It's not a frequent subject matter, probably because most people tend to write it off as a pretentious walking simulator for some reason.
