Ah man, I used to be super into text adventures around when I was 13-14, I'd even write my own up sometimes too lol. There used to be a site where you could make your own and share them with others, and I remember playing this one (unfortunately I don't remember the name) which started out as a simple escape-room setting, but then you start quickly learning that the world around you has long since been dead and I remember the ending where you ended up discovering that you were a robot the whole time who thought you were a human trapped in some kind of 40s style world.

Honestly I should get back into text adventures, I'll be keeping an eye on this thread.
