A flashback in what sense (Text, unique scene etc.)?Is it wrong to ask for a flashback about the female protagonist’s first time?
If you can describe the idea in more detail, then we certainly can consider it.
Unless you mean the first time before the game is placed in time and not a flashback to the first scene during the gameplay, then we will think about it, can't promise anything as our focus is on expanding the current segment in time and not really the past yet.
