Ah, I see what you mean. Steam’s kind of weird with adult games these days, if I’m understanding it right.
Oh, and I had another question—when you say the Prologue is remastered, do you mean all of Act 1, or just up to when the MC reaches adulthood?

Yes... If you do a quick google search you'll understand what I mean about Steam (New rules)
The remaster will be the Full Game Act I + Act II, but right now you can consider the Prologue like some sort of DEMO that ends right before the path split. When the MC is attacked on the Ship before he wakes up with Bredita/Isabella/Ayna.
