NYX:ARG is a browser-bound alternate reality game.

My glitch artist friend nyxphaea on instagram posted a cryptic story with base64 and binary-encoded messages, and my neurons activated to the point I built an ARG game around it.
Explore the Memory, Index, Signal, Human and CONDUIT sections to progress.

The Signal section is where most of the progress happens - it is a terminal you need to interact with - read HELP, type stuff into it, observe what it tells you, and adjust the puzzle-solving accordingly.
I will admit - it took me over an hour to solve this ARG myself as the creator of it, so it might be hard. Still, I believe you can do it.
The reward? For now, proof of completion certificate in text and downloadable PNG.
If this picks up, I will build on that.
