I just finished Sofia's route, and to be honest it's one of the best visuals novels I've ever played. I really loved the first game too, but this improved on pretty much every aspect of it.
I absolutely love the MC in these games. She's genuinely intelligent, witty, and a bit devious. I love of much freedom is given to the character too. I felt like I was able to really express how I thought she would react to various situations.
The way the relationship between Sofia and the MC is written is also excellently handled. You can't help but fall in love with this pairing. It's so rare to see a game where you get to play after the relationship has started. Even rarer to see a game where a continued relationship between characters feels like the characters have actually grown together. The witty banter between them is super adorable. When they argue it doesn't feel like plot contrivance or drama as it often does in VNs. It makes sense why each character would have the perspectives they do, and it's great watching them try to work through that. It's believable regardless of how things turn out for them.
Also worth noting how well the same-sex angle of the relationship is handled here. As a lover of yuri games, it's refreshing to see a game tackle some of the deeper emotional and social aspects of the relationship, and the struggles the characters face.
And of course the rest of the cast is amazing too. Frederique is one of my all time favorites. Same goes for the Duchess. She's a genuinely intimidating foil to the MC.
Thanks so much for this game! Can't wait for the rest of the routes.
