One of the main reasons why I create my games is to tell stories. Chris and Beryl are distinct characters (with their own backgrounds which will be explored through the course of the game), and it's important that this story is experienced from Chris' perspective for the main part of it.
I plan to keep creating games, and I'm sure some of them will have female protagonists - it all depends on what works more at that point in time, for that specific project.
If having a female protagonist is important to you, you can give SoulSet a try (my first project that's already been released) - there's a strong female lead there.
Hope that helps and thank you for the kind words! :)
