Thanks for playing!
This was originally for the Dying MMO gamejam and it was very rushed.
As for the text, the "lore" is that the game servers are shutting down, and you are experiencing the last moments before they close, so it is technically set in current times. Stupidly, I forgot to mention this anywhere in game.
There's not anything else to do besides walk around and explore. I haven't tested it on Linux, but I'm happy to see it works somewhat.
