UIN is a free surreal adventure game made in Game Maker by the indie cult developer Matt Aldridge, under the handle Biggt. Aldridge is best known for his mind-boggling experimental series LaLaLand. You play as an unnamed boy with scraggly, sparse hair who follows his brother into a cupboard to figure out what he's up to, only to find yourself trapped in a depressing, monochromatic, monster-filled dimension, eventually unraveling an abstract grasp at what your family's been up to.

Though Biggt, under that alias, seems to be AWOL, you can still download the game from [[http://sandbox.yoyogames.com/games/123139 here]]. The GameMaker Community thread for UIN is [[http://gmc.yoyogames.com/index.php?showtopic=470800 here]]. As of 2010, the game is at version 1.01.

----
!! ''UIN'' contains examples of:

* AllLowercaseLetters: the dialogue. Often ops out of punctuation, too.
* AnotherDimension
* BerserkButton: giving your brother [[spoiler: the doll.]]
* BizarroFiction: Most of Biggt's stuff is.
* CreepyDoll: The boss after the sail boat area.
* CreepyGood: the jagged-outline, balding protagonist.
* DamselInDistress: the scientist's wife.
* DeliberatelyMonochrome: The only colors you will see are purple and the skin color of the man in the TV.
* DownTheRabbitHole
* EldritchAbomination: Capybara, the large, spidery legged monsters who appear out of no where and take up the height of the screen, spew what appear to be swarms of flies from their orb weaver stomachs and have peanut-shaped heads with perpetually screaming mouths. If you hit them once, their body will disappear, and their head and all its wonderful gnashing teeth will come flying after you.
** Also the [[spoiler: okapi, enormous maggots whose presence is preceded only by eerie scratching as they crawl across the map. Not only do they follow you through rooms, but to defeat them, you must shoot a place appendage into their mouths, upon which they will spew the black fly matter and several teeth-like creatures which attack you.]]
* FakeDifficulty: The wacky controls will kill you quickly and often. Especially since enemies can often catch up with you when going between different "rooms" on a map and your recovery time is almost nonexistent. Not to mention your hit box is pretty large.
** A lot of players have trouble figuring out how to get the DIG ability. You just have to [[spoiler: kill all the spiders in the cave.]]
* {{Foreshadowing}}: the knickknacks around the bedroom you start in are the spitting images of the enemies you fight in the game.
* FungusHumongous: in the background of the area where you unlock the chest.
* GameWithinAGame: the clam game.
** [[spoiler: Special mode, in which you play as your brother, sending minions from a hovering ship in order to destroy fish people. Apparently it's impossible to win.]]
** Kites. Though at least they're better than [[spoiler: Limpkins and Orioles.]]
* GottaKillThemAll: Though most enemies spawn in droves, each species comes in a finite number. After you've killed at least one, pressing space will bring up a menu that keeps track of how many are left. Eradicating a species can sometimes give you an ability that's needed to progress through the game.
** In fact, in order to open [[spoiler: the door in heaven.]], you must kill everything.
** Subverted when [[spoiler: unlocking Special mode,]], when you have to get to [[spoiler: your brother's house]] without having shot a single enemy.
* GuiltBasedGaming: when you lose [[spoiler: Special mode, you see Father in his chair saying, "Why?" before exploding. Because of your failure.]]
* HeartContainer: Several found by digging, scattered randomly throughout the game. You can buy maps that give you hints on their locations.
* ItMayHelpYouOnYourQuest: the PUSH ability.
** [[spoiler: Later, the scientist in space gives you a bomb at least three times your size.]]
* LeapOfFaith: Into a puddle of quicksand early in the game.
** In the cave, jumping down beneath the black sun takes you back to the cupboard entrance.
** The cliff past the bird's nest is a 1-hit KO [[spoiler: if you ''jump'' off.]]
** The baby bird drops you off ''in a volcano.''
** The cliff by the rocket ship.

* LetsPlay: at least [[http://www.youtube.com/playlist?list=PLCE1AC618C78D8346 one by ShutUpSoli]], with another [[http://www.youtube.com/watch?v=KsvVWFe3fQY started by Sinuyan]].
* LifeMeter: has a penchant for emptying ''extremely'' quickly.
* MiniGame: there's a slide puzzle of a TV with a man's face. [[spoiler: Which happens to be your father.]]
* NoodlePeople
* OminousMusicBoxTune: It first appears as a boss theme, but then plays during most if not all of the future cutscenes.
* PublicDomainSoundtrack: When you die and go to heaven, the soundtrack is the opening measures of Debussy's Clair de Lune.
* SadisticChoice: In order to progress past the cave, you need to [[spoiler: lure the nuthatch into a black sun, presumably killing it, so you can steal its egg.]]
* ShoutOut: the mustachioed fish man running the clam game is eerily similar to the one from ''La La Land 2.''
* SoundtrackDissonance: the underwater area features a desert-esque bgm with wind sound effects. You know, for water. The airiest place that can be.
** In the area where you land after being shot out the volcano, you are tasked with completing a slide puzzle to some of the most absurdly epic space music ever.
* SwallowedWhole: At one point underwater, you can swim through the open mouth of an enormous fish. Incidentally, your brother has a house inside its spacious stomach. It even has a mailbox.
* ThemeNaming: Sort of. Most if not all of the enemies are named ironically after species of animals they are most definitely not. The large screetching buzzards, for example, are called nuthatches.
* TroubledFetalPosition: Your brother after [[spoiler: giving him the doll and meeting him in the rocket ship area cave.]]
* Understatement: "aw geez..."
* UnderTheSea: the volcano, strangely enough, leads to an underwater area.
* UnexpectedShmupLevel: the sky.
* YankTheDogsChain: The main character only goes through all this because stuck in a dimension of hostile monsters and has no idea what to do. After dying a myriad times (the game actually has a death count after you finish it) and exploring a surreal dimension -- while being constantly belittled by his brother, no less -- he ''finally'' can go back home, only to find out [[spoiler: those monsters he killed were what was keeping his father alive.]]
* YourHeadAsplode: [[spoiler: Father,]] after both [[spoiler: beating the game]] and [[spoiler: losing Special mode.]]
