Help finding an old text based game - lemm.ee

There was a post on lemmy a couple of weeks ago about an old, hard, I think text based game. I wanted to look it up but forgot the name and I can’t seem to find it anymore. Any help with this would be really appreciated.

It would help if you were a little more descriptive. Like is it something similar to knights of pen and paper? A dungeon and dragons kinda game?
