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.
Anti-Climax Boss: Much like Shadowgate, the room directly BEFORE the final boss is much more difficult than the last battle itself.
Big Lipped Alligator Moment: The guardian of the Blothney Gem. Even the game itself has a difficult time trying to explain what it is and what it's doing there.
Ensemble Darkhorse: The Ghost Lady is your first 'enemy' and once beaten, she'll disappear from the plot. But she's the one thing everyone remembers from the game.
Hell Is That Noise: If "UH-OH!!" could be could be expressed in musical form, it would probably sound just like the NES version's death scene music.
On the Mac, failure is punished with what sounds like the Reaper himself proclaiming, "I've got you!"
