Easily one of the best visual novels I've read (and I am a big fan of the medium!), this is a fantastically written and visceral dive into isolation, cycles of abuse and mental illness. It is especially written with a lot of respect and care, especially regarding the mental health issues, sympathetic and less so, faced by all of the characters. The dread is at times palpable, the characterisation and dynamics superb, and the after-materials really expand upon the story whilst also allowing the main narrative to stand as is. I've been hovering around getting into denpa VNs for a while, and I'd definitely recommend this as an entry point into the subgenre!
