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.
Breather Level: The entire "Vivi's Funeral Salon" sequence, in which you encounter over a minute of dialogue before an easily-avoidable death by spider. From then on it results in more dialogue and pretty much less of the "Press X to Not Die" scenes, one of which (the "deadly manicure" scene) is pretty difficult to master without noticing Vivi's clumsy finger-pointing clues. Otherwise, it's a bit of a relief in this level.
Ear Worm: Pretty much of the soundtrack. And it's on the playlist here.
Faux Symbolism: One of the resurrection scenes (in case Lance dies in haunted rooms) shows the "fires of rebirth" reform Lance's body and restore him to life. This is a bit strange, as it is kind of reminiscent of The Phoenix, which is an ancient and well known symbol of death and rebirth and portrayed as a magical bird made of living flames; the story says that when a Phoenix reaches the end of its life, it would make a cinnamon stick nest and self-immolate itself with fire, and from the ashes a new Phoenix is reborn. This could explain the "fiery" resurrection scene that Lance, like a Phoenix, can rise from the ashes of defeat and start over. Weird.
Nausea Fuel: In one death scene, Fritz sticks Lance's head in a blender, then turns it on, purees his entire body, and drinks it like beer, eyeballs and all. This is just so barf-worthy.
Polished Port: The Philips CD-i, 3DO and PlayStation ports of the game have higher video qualities than the MS-DOS, Windows, Atari Jaguar, and Sega Saturn ports, though the former first three each have two CDs instead of one; but only the iOS port, which does not require any CDs, has a higher video resolution that surpasses all of the earlier versions. Also, the 3DO port has two versions of Disc 1: the original one, and "Version 1.1", which fixes a bug that would sometimes cause a crash in Vivi's Salon in the original release. The iOS port did the same in December 2010 by upgrading its version from 1.0 to 1.1, which added support for iOS 3.0 and 4.2 and fixed various bugs.
Porting Disaster: The Jaguar port, on the other hand, has a very low video resolution and blocky graphics than all the other ports of the game.
Moose giving Lance a wedgie that splits him in half and rips out his spine and pelvis.
That One Level: Moose's entire scenario. It starts when you enter Moose's room and, immediately on entering it, you notice a stone football getting thrown into your mouth if you don't avoid it. Once you get past that football, you have to dodge another football, along with Moose's grabs, shoulder charges, baseball bat attacks, being flung by a basketball net as a catapult, and the grab from below his head, all in the first quarter of this scenario (followed by a lot of Deadly Dodging of the lightning rods in the second quarter; finding a way to destroy Moose in the third quarter; and dodging Fritz as usual in the final quarter)! Failure to avoid any of these attacks in the first quarter of this scenario will send you all the way back to where you entered the room in the split-second that the same stone football is getting thrown into your mouth again!
What Do You Mean, It's for Kids?: It's a game where the protagonist gets to die in all sorts of graphically violent ways, which has made it extremely hard to understand why this was given a K-A rating note (Kids to Adults, the mid-90's equivalent to the Everyone rating) then. (Some could argue that "it's because it looks so silly" but many of the deaths were not exactly all that light nevertheless so in other words the fact that this game was given a K-A rating might be considered to be really... baffling to put it mildly.)
What's even stranger is that Japan's game rating organization (pre-CERO) slapped each box of the game (exported from America) with an "all ages" (全年齢, zen nenrei) rating on a green sticker, hoping that its audience of children would be less sensitive to mind-numbing bloodless violence and sexuality than America's children (due to cultural differences).
The iOS port thankfully averts this by ramping up the rating to a 12+, which could be an equivalent of either a "Teen" or an "Everyone 10+" rating.
