History VideoGame / KnockKnock

* [[SpeakingSimlish Speaking Gibberish]]: The Lodger's speech is always a series of garbled high-pitched mumbles. [[spoiler:Other characters speak normally, however.]]
** [[spoiler:It should be noted that the Dopplegangers that appear from time to time seem to have the same voice actor but speak coherently.]]

* DarkAndTroubledPast: The Lodger and his family have one. Each of the Lodger's ancestors added a room to their ancestral home, but the Lodger claims not all legacy is good and rarely goes into some of said rooms. As for the Lodger himself, it's unclear. [[spoiler: Who ever they were written by, the diary entries that can be found after a certain point in the game claims the author's son and two unrelated children lived in the house and were being hidden from the government. They were eventually found out and taken away, and then soon afterwards, a little girl(?) appeared in the house. Her body was seemingly invisible, she didn't appear to need to eat, and she was wearing white clothing. The diary author wonders if she was a product of government-run experiments. One day she brought the diary author brown leaves and he had as much of an idea as to what that [[MindScrew meant as the audience does]]. It's hard to be sure whether the diary author is the Lodger himself and the children were his to take care of, or if he is the mentioned son. Either way it suggests a less than happy history attached to both the Lodger and the house itself.]]

* MindScrew: Good luck trying to figure out what's going on. The only clues you get are [[UnreliableNarrator The Lodger's monologues]] and some diary pages, and even ''those'' rarely give you any information whatsoever, unless you look for specific ones. Unlike many games, though, this also can be said for the game-play. Was the girl another construct of his mind or a product of [[spoiler:government experimentation? Was there government-sanctioned child kidnappings or was it in his head]]? [[UnreliableNarrator Did the Lodger actually have a son, was ''he'' the son, or was it all just another fiction?]] Is he actually a "world-ologist" who is paid to watch the forest or is he just a madman in the woods? To quote WebVideo/{{Markiplier}}, the game is a bunch of loose threads that don't connect or are fully explained. Several ideas are thrown out there and many of them contradict others.
* MissingMom: According to the Lodger's diary, he was a father, but his wife is never mentioned. [[spoiler:His child, as well as others, was taken by the government before the story's start.]]
* NonStandardGameOver: It's virtually impossible to get a game over in the levels that require you to avoid ghosts, as they simply restart the level. Later in the game, however, wandering the forest without care can get you a game over screen with the Lodger apparently [[GoMadFromTheRevelation gone mad]].

** [[spoiler:It should be noted that the Dopplegängers that appear from time to time seem to have the same voice actor but speak coherently.]]

* VagueAge: The Lodger's age is never stated. Physically, he looks like a kid, but verbally, he sounds like an adult. [[spoiler:The diary entries suggest the latter.]]

* {{Bizarrchitecture}}: The house becomes this in later stages, as it grows in size but retains the same random generator. So you'll see basements going five stories deep or towers that connect each other in bizarre ways.

* BreakingTheFourthWall: Whenever the Lodger speaks, he turns his head to the camera. It's never really stated whether he's talking to himself or actually talking to the player. There are instances, however, when he seems to talk to ''someone'', like pleading for help.

* DarkAndTroubledPast: The Lodger and his family have one. Each of the Lodger's ancestors added a room to their ancestral home, but the Lodger claims not all legacy is good and rarely goes into some of said rooms. As for the Lodger himself, [[spoiler: who ever they were written by, the diary entries that can be found after a certain point in the game describe someone's son and two unrelated children that lived in the house who were being hidden from the government.

* PerpetualFrowner: You see the expression on the Lodger up there in the page image? [[UpToEleven He wears it for 90% of the game]].
