!!SPOILERS!! does anyone know how to start the secret route? I've completed all the routes and all their endings (I think) I've unlocked Liens route so I know I've done Xanthes, Baes, Lyells, and Victorias correctly. (I know I have all endings for them) but I think it might be Lien that isn't letting me progress?? I got the good ending, the one where you give up instinct, the one where you lose your memory, and the one where Lien kills you in the forest towards the start of the route. I think that's all of them but I can't unlock the secret route for the life of me, I also have all the girl's trinkets/items on the main menu. So does anyone know the reason why?
(Also Spoilers) It's been a while since I played this but what I did was go to just before the common route ended and went back little by little until there's a new option appearing when you speak to Blake at the end of the common route. I completely missed the option when I tried to get it right after finishing everything for Lien.
