very stunning game. also i think i found the easter egg. i don't want to spoiler things to those who haven't played the game yet, but in the somnium os, click the recycle icon, you'll notice a file called "freewifi.cmd". it will respond with "hold up". same thing with opening cmd and typing "freewifi".
edit: also, if you typed help 2, and scroll down a little bit you'll see a message called "secret: GET WIFI ANYWHERE YOU GO (freewifi)"
yet another easter egg; type in "help cheats". this will give you a list of cheats inside the game (not recommended for first experience)
i think the devs were referring to this one cursed meme that the gen z has taken over lol. great game tho!
