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.
Hell Is That Noise: Quite a few ambient sounds are very creepy but don't mean much. One sound, however, comes from the cute Mokos that Eva throws around. When a monster starts chasing her, the Moko she is holding lets out a squeak of terror. Heard as a standalone sound, this squeak comes off as merely cute, but when this happens when the area is dark and the monster is behind Eva, it can be quite terrifying, especially when the screen turns red signifying Eva's terror.
