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.
YMMV: White Day: A Labyrinth Named School aka: White Day
Scrappy Mechanic: The mad cackle that starts playing in a loop after the tentacle tree graps your love interest. It will continue until you solve a certain puzzle, which is incredibly hard to figure out since it depends on finding a tiny key hidden away in a small room. Depending on how quickly you find the key, this can mean that the same laughter will play in a loop for several hours. Which has caused many people to rage quit.
Nightmare Fuel: The fact that the game developers actually had to make patches people could download, to make the game less scary, because people were complaining that the game was too terrifying should probably tell you something. One particular example would be the face of the ghost that emerges from the walls early on. It can be very terrifying if you manage to get a glimpse of it in dim light.
