Sorry for the late reply, itch for some reason flagged bunch of comments and they weren't shown to me. The ????? option does nothing with no way to unlock it, it was supposed to be a part of ARG, but due to my ex cutting the development short in a way, I had no time to implement all the ARG content I wanted to, including this option. Really sorry for it being so disappointing. The 2.0 may or may not have some better ARG/lore, though.
