A horror game created by Ice-Pick Lodge, the same folks behind Pathologic, Turgor, and Cargo! The Quest for Gravity. The game was successfully funded through Kickstarter, and can now be purchased on Steam.In Knock-knock, you play as The Lodger, a disturbed young loner, as he's caught in a nightmarish loop of suddenly waking up in an unfamiliar house again and again, without the security of knowing what's real and what's just a part of his dream. But with those visitors after him, who cares? Whether it's all real or not, the only reassurance he'll get comes with the dawn.The basic gameplay is simple, but the game doesn't hold your hand through even the basic mechanics. You wander through a randomized house avoiding horrific monsters, as you run the clock out until dawn. Hiding rewinds the clock, and you can only hide behind furniture, so sometimes it's better to outright run. For those that want to figure it out for themselves, as the game pushes you to do, all further mechanics have been spoilered. When your character closes his eyes, things come into existence. Sometimes, it's only furniture.Needs Wiki Magic Love
This game provides examples of:
2½D: The rooms are 3D with interacting shadows and objects, but you can only move in two dimensions when not moving between levels.
Attack of the 50-Foot Whatever: Reaching the monster symbol on the 'map' brings a giant entity that looms over your house for the remaining length of the game. Whether this is the monster shown in the trailers or the local ghost girl is determined by your willingness to do some side-tasks and has an impact on the ending.
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.
Difficulty Spike: After reaching the 'monster' symbol on the map, the game gets a lot harder. Not only do you get a lifebar of sorts, the game throws in enemies that are faster and can follow you down and up the stairs. On top of that, the forest gets populated with (unmoving) monsters and throws a time limit at you.
Evil Laugh: Happens every time you walk into a ghost.
Gainax Ending: Both endings are brief, thirty-second clips that will only make things even more confusing if you haven't riddled out the game's symbolism and found (and memorized) all the diary entries. They revolve around the house as a representation of the Lodger's mind, and the monsters, the Bogeyman in particular, as his repressed memories of what happened to the orphan girl during the mass abductions.
Pagurian: Obtained if the Lodger avoids seeking out diary pages and Fragments of Reality in favor of staying safe and avoiding hostiles. As the Bogeyman draws closer, the Lodger decides to shut himself inside his house.
Break the Cycle: Obtained if the Lodger collects Fragments of Reality, looks for diary pages, and seeks out the weeping child Guest who appears in the later stages. The Bogeyman turns into the the girl, the Lodger decided to leave for some reason, leaving his house and the rotting forest behind.
Mind Screw: Good luck trying to figure out what's going on. The only clues you get is 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.
Trailers Always Spoil: The game trailers pretty much give away most of the designs for enemies - something vital in most horror games. Averted when it comes to any sort of, plot though.
Non-Standard Game Over: 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 gone mad.
Sanity Meter: One appears after the arrival of the Bogeyman. It drains slowly whenever the Lodger isn't in his home, and it's persistent for the rest of the game — if it runs out before the very end, the Lodger loses his mind the next time he tries to go outside, forcing the player to start the game over.
Sanity Slippage: The Lodger is a bit off-kilter at the best of times, but after the Bogeyman appears, his brief voice clips become more and more deranged. You get a Non-Standard Game Over if he slips all the way, since he's too exhausted and terrified to leave his own house.
Sleepwalking: The Lodger blames the first few oddities on this.
Stringy-Haired Ghost Girl: Can be encountered while wandering around the woods. Walking into her allows you 'catch a glimpse of the other world'. She can also appear over your house to indicate which ending you'll probably get.
Speaking Gibberish: The Lodger's speech is always a series of garbled high-pitched mumbles. Other characters speak normally, however.
It should be noted that the Dopplegangers that appear from time to time seem to have the same voice actor but speak coherently.
Vague Age: The Lodger's age is never stated. Physically, he looks like a kid, but verbally, he sounds like an adult. The diary entries suggest the latter.
The Walls Have Eyes: Some rooms have eyes scribbled on the walls or ceiling. Also used to symbolize a 'breach'.
