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.
Continuity Nod: In fact, some of those noises reproduce the melodies of several tunes from the first game, or ARE tunes from the first game after having been worked over with a sledgehammer. This" might be Fridge Horror for players of the first game.
Nightmare Fuel: The entire game - surprisingly effective for a point-and-click adventure rather than more traditional action-oriented Survival Horror. The realisation of what you're about to find in the hollow lion (it's Merrick's body) as you stand directly in front of it reading the final diary entry is a good example; as is the music, particularly the track which incorporates a woman's anguished screams and her repeated cries of "Help me!" into the score.
Tear Jerker: The story behind Anansi The Spider. Windlenot was so enamored with the tune when he first heard it, that he decided to make the music box for his son Geoffrey.
