So for anyone confused by the sudden name change of the game making it look like they are trying to sell a different game? It is fine, it IS a content update. But seems they were just clumsy about getting that across.
If you want english for the new game Maternal Monsters, Options, 4th down lets you switch to english.
Maternal monsters even lets you run witch succubus inside of it with a teleporter off to the side. "Why is the download smaller then?" because Witch succubus DL is the windows and mac version in a single zip, instead of separate downloads.
(I am getting such "Mother sending an email you know is legit, but did everything in their power to make it look like a scam at a glance" vibes).
