MAAAAAAN it's so well done, the music, the drawings, de characters. It's everything so well used for creating tense atmosphere(and destroying it lol). I still didn't finished my first go, but hell there are so many mixed feelings in my brain. 10/10 One of the best visual novels I ever played (if not the best).
PD: if you didn't play it yet, be careful with this comments section for spoilers ;)
