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: Limbo of the Lost
Alternative Character Interpretation: rpg.net forum users seem to agree, that Captain Benjamin Spooner Briggs is a cultist of Elder Gods, who forsaken his sanity long before the events of game.
Fridge Brilliance: People have pointed out the nonsense of Briggs being "Destiny's weapon against Fate", given that the two are practically the same thing. However, this does make a bit of sense when one considers that they are portrayed as brothers, and if one takes Destiny to mean positive predestined events and Fate to mean negative predestined events.
Memetic Mutation: The plagiarism charges led to a brief fad of photoshopping the main character into other games. Rock Paper Shotgun even held a contest seeking these.
Mis-blamed: The writing and "logic" of the story are so crappy as to be beyond excuse, but there are a few common places where the storyline and/or Briggs gets unfairly criticized. Perhaps the easiest to identify is that of Quagmire the chained prisoner in Chapter 2, who you free. A lot of criticism has been directed at the fact that you are freeing a chained prisoner without supposedly knowing why he has been imprisoned, but you actually can find out in the previous chapter. Of course, considering the millions of actual issues with the storyline, this is a very excusable case.
And even it is slightly debatable if Grunger's note in the prologue actually refers to Quagmire - the name on the note is "Jethro Quagmire", when Jethro is the name of the janitor in the Machine chapter. An intentional case of defying One Steve Limit, or a continuity mistake? Only the developers know.
Which may be giving them too much credit.
Another example (also referring to Grunger) is having to put sleeping snot in gruel when the jailor's already asleep. Grunger may be asleep when you encounter him, but Ed refuses to let you pass until you feed him (threatening to have Grunger kill you at least once), and it'd be pretty much impossible to get past Grunger when he's awake.
In Chapter IV, have fun hearing this announcement every time you use the train:
Ladies and Gentlemen we have now arrived at <location name>. Now please ensure you have taken all your belongings with ya. I hope you've enjoyed your travel with Wreck and Ruin Railways and uh... we get ya there...eventually.
The ending song.
Narm: If the horrendous spelling in the subtitles doesn't get you, the "King of Limbo" song at the end will.
Before Briggs meets face to face with a Cerberos-like monster dog in the first level, he finds his bowl first. It's got a pentagram engraved inside and the label "Fluffy" on the outside. In the font from the Buffy the Vampire Slayer logo.
One of the NPCs (an old, hag-like woman) is named Cranny Faggot. Yes, really.
The finale of chapter three has Briggs unmask the Soul Taker who has been terrorizing the citizens of Darkmere... by literally ripping off the human skin the (very non-human-shaped) monster had been wearing as a disguise. Thanks to the lacking animation, it ends up looking like something out of Scooby-Doo. Intentional homage that fell flat or just bad writing? Who knows, and frankly who cares.
Nightmare Fuel: A lot of the faces are horribly creepy, such as Briggs'.
Special Effect Failure: At one point in the prologue, Briggs enters a hallway at which the camera is tilted at an angle. He is (very obviously) not angled.
Later, in the aforementioned "sewer" chapter, the developers tried to cover up the fact that Briggs is actually walking on top of the water by overlaying a cheap-looking dithered pattern over his feet.
Ohhh, there's lots. When you're working with purchased Poser models on 2D backgrounds, there's no limit to the failure of the special effects.
One of the most obvious issues that persists throughout the game is the layering of text onto round objects. Many, many times through the game, there will be bags or round bottles with flat text. Nothing in this game has any real attempt at special effects.
One particularly hilarious note about the game's visuals is that the behind-the-scenes featurette on the bonus DVD makes a big deal about the game's dynamic lighting effects. It's just too bad the light source or the characters' positioning have no bearing on how the shadows actually fall.
They Just Didn't Care: For some reason, despite sinking 13 years of their lives into this, the developers never bothered to learn how to properly program or make their own art assets. You'd think if they cared about the game that much they'd put in some effort, but apparently not!
Uncanny Valley: The CGI was never very good in this regard, but that final song... welcome to the nightmare, kids!
