WOW, I've been playing nonstop since it came out on Monday, and have gotten 4 endings so far.

This game and this route in particular is a masterpiece!!!
I noticed that there were hints of Guillaume easy to anger/righteousness issues in the first game, but it was really shown here.
While this route didn't offer a differn't LI option, I was happily surprised by the MC's mother's more emotional side. Her love and fear regarding her children's safety as well as her empathy were more apparent in this route and I loved seeing it in combination with her schemes.
The way you mold and show various sides to these characters and to the ongoing conflicts, situations, and drama through various decisions/personality / traits the MC has in this route (and have them intersect through other routes) is incredible.
You have a masterful storytelling ability and thank you for your hard work on this project. I've really enjoyed playing this game, it is by far one of my favorites.
