These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Most Annoying Sound: After a while, the high-pitched "mental transference" sound effect gets really grating.
Nightmare Fuel: Bad End #8, in which Yomogi goes crazy and kills his way through the shelter cabin residents until Kokoro decides she'd rather run out into the middle of a frozen wasteland to die than be left alone with him. Also, any of the endings where Utsumi kills Hotori.
Squick: Utsumi was only fourteen years old when she gave birth to Junichi. Seiji would have been twenty-three at the time. On another note, they're Happily Married.
