IF I could do the game all over again, from scratch, a lot would change, especially how I set things up during the premise. Everyone will no longer stay with you in the same house, only Klara and Sky (I'd still keep the childhood friend and guardian thing because that's the most essential part of the main story).
Aine will come looking for you herself through Emma. She'll try to make peace with you, and we'll take things slow from there. Instead of entirely moving on from the past, she'll redeem herself through your character dynamics and such.
Emma and Gwen will come follow in the middle of it.
Introducing Moon and Freya to the story later on.
Chapter 1 - Episode 1 will be moved to Prologue.
After that, I'm satisfied with what happens further into the game.
Remove Lily and Naomi from the story. They were unnecessary characters added on impulse.
