So... I finished the game again... This time focusing the newest routes.
Xanthe's route was different from what I expecting... in my vision she was vamp seducer fighting her urge to drink Jay's blood,in yours she had problems with some kind of "demons" the past but you also made a lot of place for romantic stuff
Lien route is much crazier than I'd ever imagine... Fighthing with inner beast, unpleasant past and "science". And asshole behavior adds her a lot of charm.
Super-secret route was great... I'd expect Tailor or Sherrif or someone completely new, thinking that Blake would be too obvious choice. Well, she's normal, boring human... I was sure it gonna end right after making-out scene... but... everyone must have their own villain to fight.
Also Jayline got some more character development with each route. Finishing them all is key to complete understanding of her.
