This game was awesome! You've absolutely nailed the aesthetic - the dystopian brutalist architecture is so well executed and really gives you a sense of scale and loneliness in the world. The environment itself is half the world building - very impressive. You've basically made 2 games in 1 here too, with the terminal minigame! I can totally see this becoming a full game. Add some more levels and get it on Steam.
Just thought I'd let you know, the credits seem to be broken. It looks like you've entered markdown but it's just showing up as plain text. Other than that, can't believe how polished this is! Really nice work :)
