Catherine is, for me, a truly strange game in the world of video games, one that I really enjoyed.
This version was released on PS4 and adds additional content, such as new blocks to create more mechanics, and above all, adds a brand-new character nicknamed Quaterine to the story, which further fleshes out the story and offers additional endings along the way. And I don't understand why there was never a port of this version to PC (there's only the Classic version)?
