History YMMV / SpookysJumpScareMansion

** [[spoiler: In the "bad ending" the player character ends up becoming another Specimen, showing off their longish hair, red eyes, and a [[AxCrazy blood-stained axe.]] Because of this, some players have compared them to Chara/the fallen human from ''VideoGame/Undertale''.]]

** Some find the new Specimen 10's worm form to be this.

* SignatureScene:
** Arguably, the [[KaizoTrap endless hallway]] that Specimen 9 resides in.
** Also arguably, the encounter with Specimen 6.

* SpiritualLicensee: The game is probably the closest thing to a video game adaption of the CreepyPasta ''[=NoEnd=] House''.

* [[{{PopularWithFurries}} Popular With Furries]]: Not the game itself, but Specimen 8 seems to be pretty popular with furry artists. Most of their popularity seems to come from [[{{SelfFanservice}} Self-Fanservice]].

* BrokenBase: There's a fairly small one over whether the animated 2D sprites from the original or the full models in the ''HD Renovation'' are superior to the other.

** The cat that appears before you encounter Specimen 7. A lot of players found her design cute and the MindScew in the rooms around her to be one of the memorable parts of the game.

* SignatureScene: Arguably, the [[KaizoTrap endless hallway]] that Specimen 9 resides in.

* MemeticMutation: [[MakesJustAsMuchSenseInContext Better Ingredients, Better Pasta, That's the Power of Home Depo]].

* CounterpartComparison: The protagonist in the [[spoiler:Specimen Ending]] has been compared to [[spoiler:Chara]] from ''VideoGame/{{Undertale}}'' due to a similar hairstyle, ambiguous gender, and the means of reaching this ending. Similarly, Spooky and [[spoiler:Flowey]] from the same game: [[spoiler:both were relatively normal people who got killed due to a tragic misunderstanding, then were reanimated only to [[CameBackWrong return as]] [[AxCrazy bloodthirsty]] [[TheSociopath sociopaths]]]]. In addition, Karamari Hospital heavily resembles [[spoiler:the True Lab; from the intro involving the protagonist falling down an elevator, to containing 5 new monsters, to revealing the backstory of the respective main antagonists]].
** The [[spoiler:Specimen Ending]] has also lead to comparisons to one of the endings from ''VideoGame/SCPContainmentBreach'', where the player character is similarly [[spoiler:classified as an SCP. Though, unlike Spooky, it's not due to their violent nature, but because of their surprising ability to navigate the Foundation while under such circumstances.]]

* CrowningMomentOfHeartwarming: When you really think about it, Spooky including Lisa from P.T. can count as one, because it essentially means she gave an abandoned and unappreciated horror villain a new home to scare audiences. In similar vein, Spooky adopting [[VideoGame/ImScared White Face]] in meant that [[EarnYourHappyEnding he finally has a place to call his own with willing people wanting to "play" with him.]]

** Specimen 8 is also pretty popular, due to its unique design, looking like a deer {{Wendigo}} with an AllEncompassingMantle. It also has a [[CrowningMusicOfAwesome pretty cool theme]] and has some pretty disturbing lines when it gets close.

* AwesomeMusic:

* TheScrappy: Meanwhile, Lisa is arguably the closest to this in comparison to the other Specimens and Monsters. This comes from her [[ThatOneBoss absolutely tedious and frustrating chase]] [[GuideDangIt with confusing rules for escape]], and her {{Leitmotif}} is only considered just okay by the majority. [[RecurringElement Being the second enemy that's essentially an even stronger Specimen 6]] and her [[Squick disgusting death screen]] don't help matters either.

* AntiClimaxBoss: A few specimens can be like this but Specimen 10 had it the worst. One reason was that this specimen was so late in the game, after a couple very dangerous specimens. Another reason was that its design can be dull to some. Just a white snake with a generic face that really has no gimmick at all. This came after a huge, atmospheric, buildup. The developers have acknowledged this, ultimately replacing it with a more intimidating monster.
* AuthorsSavingThrow: After the lackluster reception of the original Specimen 10, the developers decided to replace it with a much more dangerous and terrifying Specimen. There is even a little TakeThat to the previous Specimen 10 by the new one literally popping out of its head when the old one spawns. WordOfGod admitted that the original design of Specimen 10 was the result of them running out of ideas.

** Specimens 3, 7, and 10, which are considered much more easy to avoid compared to the Specimens that come before and after them. Ultimately averted with the introduction of the ''new'' 10.

* GoddamnedBats: The actual [[JumpScare jump scares of the title]] are completely harmless in and of themselves and easily maneuvered around, but when you're running from something else, they can appear and obstruct your path at any time. For a split second, they make your character stop, likely surprised by the jump scare themselves. This is not helpful when running from something.

* LoveToHate: The new Specimen 10, which fans jokingly hate for killing the old Specimen 10. Jokingly because despite this, people legitimately like the Specimen for its [[BodyHorror disturbing appearance]] and unique chase mechanic.

* UnexpectedCharacter: For a game that is a love-letter to horror tropes and games, nobody expected it to have an actual GuestFighter since the specimen are instead [[{{Expy}} expies]]. Enter [[VideoGame/{{Imscared}} White Face]] in Endless Mode.

* AlternateCharacterInterpretation: Spooky herself. Her backstory reveals that on one Halloween, after not being able to scare anyone with her costume, she does ''something'' that involves firing a gun. It's not clear whether she used the gun on someone or if she finally managed to scare someone and got shot for her trouble, as one of the trailers show that even her ghostly appearance might be a facade. Or not. One of the endings reveals that she really is a ghost, and her entire reason for sending people into the labyrinth is to raise up an army of ghosts so living people stop calling her cute.

* HilariousInHindsight: One of the rooms contains an anime-styled dating sim that eventually starts to glitch into something much darker. Then came DDLC...

* UglyCute: The fake Specimen 10, which some fans find a little adorable despite its NightmareFace. Seems to be this in-universe as well since its CAT_DOS entry shows that it's harmless and GL Labs treats it as a TeamPet.

** It's entirely possible to go through the entire game without seeing Specimen 3 or being attacked by it. It can spawn, but unless the player is walking everywhere or they end up in a dead end it's likely they'll be out of the room before Specimen 3 can catch up. It doesn't help that Specimen 3 spawns out of holes in the ceiling, meaning that not only can the player tell if it's going to chase them before it even spawns but also [[GoodBadBugs it can get stuck in the wall if the hole it spawns from has a wall right under it.]] Most hilariously, if a Specimen 1 spawns while Specimen 3 is chasing you, Specimen 3's size would prevent it from reaching you behind the Specimen 1! The HD remake addresses this problem by making the former AnticlimaxBoss move way faster, and giving it the ability to phase through Specimen 1.
