This game is SO good, the storywriting is SO good, everything about it is phenomenal.
(somewhat spoilers)
I wanted to say specifically though that the nightmare scene involving natsumi, the use of the flashlight and the darkened environment genuinely sent chills up my body, holy sh*t. I forgot this was an h game... I don't even think it's fair to call it that. It's more of a... romantic thriller with some really hot scenes. Amazing work!
