Yes. I explore it a little in the narrative but I don't think I ever directly say what happened. The main character is a child who was left at Grandma's house by their parents one weekend and they never returned.
It's possible the parents had some financial difficulty and couldn't afford to raise their child, but it's never explicitly clear why they left. It was purposefully left hazy to reflect the perspective of abandonment and uncertainty. One can only know the resulting actions and hardly ever the motivation.
It's a maternal story, and I strongly believe that while writing it the grandmother was the child's mother's mother. You can infer from the grandmother the traits of the mother.
I never explicitly mention the child's gender or physical traits so that the player can Quantum Leap into the story with the greatest of ease - but the child is curious and lonely and they rarely interact with other children (X CHILDREN at the foot of the hill).
Playing back through the game I note other aspects that were explored about the family dynamic, like the grandfather keeping the family together until he passed away.
The village sits on a horizon that can be explored mentally but not physically. It may as well be another country from the player's perspective.
Thank you for your comments! It's been a lovely moment of reflection.
