Funny story, I actually had a sequel in mind that would delve into Galatea's whole backstory a bit more. I haven't quite gotten around to working on it, most I've got at the moment is concept doodles and stuff.
That would be so fun to play! Quick question, does the well/Pygmalion retain some of Galatea's personality/memory? Asking because "Rosa" managed to recognize her loved ones when Pygmalion possessed her but (depending on the players choice) Pygmalion shouldn't know about them?
