Great, tense writing that maintains throughout the story, despite it being quite lengthy. Many horrors fall down when it comes to characterisation, but the characters here are likeable, relatable and competent, and you come to really invest in what happens to them...
Everything is impressively thought out and with a vivid level of detail and ongoing consistency - It might require a stronger warning that 'intended for mature audiences' though - it's genuinely pretty harrowing!
Really draws the reader in, often for much longer than they intended to be reading... for a pretty exhausting experience.
Some have criticised the degree of interactivity, but this tends to vary between IFs - And I felt the act of having to decide how to proceed next made me *feel* tense and as if everything hinged upon the next decision... with characters I had really come to care about hanging in the balance.
Really well written original horror experiences can be hard to find!
