I never thought i could be scared in a visual novel, i mean, i even had to turn the lights to read it all, and the last thing i needed to read was the Cliff´s route and the end made me shit my pants xD
The only routes that didnt scared me too much are Nik´s and William´s
The most scary ones i dont know if i should choose Murdoch´s or Cliff´s one, but (spoilers) Murdoch´s one, when youre in the darkroom and see that weird image with that sound for just a sec..dude i was SCARED
