After playing for a bit, I can conclude that you will say these 2 things a lot:
1. Where the ♥♥♥♥ am I?
2. And how the ♥♥♥♥ did I get here?

In short Antichamber is a puzzle game where the laws of physics and logic do not apply. Try and survive your way through the many, many ordeals in a world where common sense is non-existent. The game offers many philosophical messages which you will completely miss as you try to comprehend what to do and where to go.
An amazing game if you want to lose your sense of logic and your sanity.

After 1 year of procastinating to play such a great game.
I don't even know why my brain decide not to finish this game last year, maybe it just got confused.
Nevertheless, now I have finished this game and learn every life lessons that is included in the game.

Every single challenge got real life advice from the dev.
I admit solving the puzzles most of the time frustated me. But you will get the hang of it when you learn how the mechanism works.
One of the advice stated "With more experience, previous challenges aren't so difficult" and that is indeed true.

Truly a lifetime experience, one of a kind and will be remembered as a masterpiece.

-If you love hardcore puzzle games this is the game for you.
-Unlike other shallow games, this one tells a story, the Journey of life -as it was first called. You slowly see it unveil as you make progress.
-The main feature that I like is that you never know what to expect in the next step you make. The map is full of surprises.
-The design is beautiful and unique.
-The game requires you to pay attention to details and think outside the box, then you will realize that the solution was right in front of your eyes. It has its own logic and its own specific style, and once you come in terms with it, you will love and appreciate every single puzzle.

-The music gave me headache after some hours into the game, so I had to turn the volume down. It's supposed to be soothing, but I personally found it a bit annoying.
-There is no Antichamber 2

If you are looking for different and brilliant puzzle game, you have come to the right place.

Some puzzles can be difficult but suprisingly not frustrating, if you find yourself to be stuck on something, you just go to do something else and things will eventually work out, sometimes you might even get to feel good about yourself for figuring it out.

Having some unusual, but clean graphics, presenting strange physics, but very accurate, Antichamber runs its own league.
It's a puzzle game that plays with your mind. When you thought you reach the end, it's just the game trolling you. You will often come back to some visited places and notice that the Matter Gun opens a completely new and unexplored path. Then you will reach a dead end and you will try new approaching techniques.
In short, this is literally mind-♥♥♥♥. But a brilliant one. You will feel really satisfied after you get past a challenge. The solutions require careful thinking and sometimes the most unexpected idea turns out to be the correct one. I have played the game more before getting it on Steam, yet I never reached the end myself.
Pros: +takes the ''unique idea'' to a whole new level;
+ challenging and rewarding puzzles;
+ the way you see the path (and this is actually a real hint) matters a lot;
+ makes you feel comfortable in its world, as you cannot die or take damage;
Cons:-after you discover most of it, there is not much that wants you to get back and replay it;
-can become frustrating at times, as some puzzles have very unexpected solutions;
Personal rating: 78/100

Well, I hate puzzle games, so I often stay away from them, mostly because I'm not too bright, and some stuff people find extremely easy takes me a LOOONG while to solve. Yep, math and puzzles are not my best.

But, this game is different. Sure, it does take a lot of thinking, so after a long while of moving around aimlessly, I said "Well, why not checking a walkthrough? ♥♥♥♥ it, I'll do it, I really wanna finish this game, but my head hurts and I don't wanna end up killing myself."

And...Jesus. This game.

I freaking love the simplistic design of it, sometimes it looks as if somebody was just drawing lines on a piece of white paper with a pencil. Sure, that looks....Bland at times. But what really shines in here, is when you are suddenly walking in pitch black rooms with bright colors, bright colors in white rooms that look like splattered ink, stuff like that. This game does really make you feel like you are trapped alone in some kind of weird ever changing place like in that movie, The Cube. The M.C Escher like geometry in here is awesome, too.

Control wise, it's the bare basics of a first person game, nothing too great about this one, but it isn't bad, neither.

Sound....Well....there is silence, silence, the ocassional ambient sounds, and look! Silence. It really builds up the atmosphere of loneliness, creepy at times, too, like in a certain pitch black tunnel.

You will frequently get lost, cry, and more often than not, you will say to yourself "Where the ♥♥♥♥ am I?"

Also, another one of the things I love so much about this game.
This game is full of signs with simple white drawings on a black background. When you click each one, you will get a phrase. All of those phrases are perfect for your everyday life, for succeeding, and for when you are truly down and depressed.

Some examples:

"Failing to succeed does not mean failing to progress."
"A dead end will only stop you if you don't try to move through it."
"When you've hit rock bottom, the only way is up."
"If you never stop trying, you will get there eventually."
"Falling down teaches us how to get up and try again"
"We can appreciate the entire journey by looking back at how far we have come."

There is 120 of those, and jeez, it's definitely one of my favorite points about this game.

All in all, definitely try it, if you love a challenge and thinking outside of the box, here you go! If you are like me, who wants to see the game and read the signs, then, there are also walkthroughs you can follow, so don't sweat it.

BTW......The ending.....Wtf. I'm speechless.

A friend once described this game to me as "learning to walk backwards." After playing it myself, I have to say this game feels more like "learning to *think* backwards."

Antichamber is a first-person puzzle game that plays with the idea of non-newtonian space. This means that if you walk down a hallway and turn around, what's behind you isn't necessarily the same as what you just walked through. There are a couple of points in the game where the only way to progress is to walk right back where you came from, which turns out not to be the same place at all.
The process of learning to deal with non-newtonian space is confusing for some, although I have to admit that I am not one of those people. If you approach each room as a puzzle and ignore your ideas of what is in front of you or behind you, (as well as some real-world ideas like 'common sense,') the game itself is not actually very difficult.
What nailed this game for me was the atmosphere. Set in what many have described as an Escher-esque world, the game's stark minimalism and use of visual space meant that even though the entire complex is built out of white walls, there was always something interesting to look at or think about. In some ways, I found this atmosphere to better than that of Portal - while GlaDos made the Portal series fun to listen to, with an ever-present and witty dialogue that provided much of the tone and narrative depth for the game, Antichamber removes the narrator entirely and forces the player to decide how much - or how little - narrative is present in the game at all. The lack of a Narrator Voice lets the game's own tone settle in the player's thoughts more closely, a tone that I can only describe at varying times as 'child-like discovery' and 'calm confusion', as oxymoronic as that last statement might seem.
Antichamber is the kind of game that is best played without a guide, not knowing where to go next, with as much or as little confusion as that might bring you. This is one of those few interesting games that can intrigue storytellers and non-story gamers alike with a dialogue and narrative that barely exist, in a setting that does not conform to the vast majority of popular videogames.

GOTY 2013!

Antichamber is amazing game that offers really hard puzzles and also meaningful notes about life in general. This game is an accomplishment since it was done by only 1 man.

I bought it on sale, but even at full price it would have been worth it.

Firstly, you do not play Antichamber, Antichamber plays you.

If you had your sanity on the way in, chances are you lost it somewhere between the chirping bird corridors, the ending never-ending circle-spiral and the 23rd time you went down that same corridor by accident (except it wasn't that corridor, something's different this time).
If you never had your sanity in the first place, you might regain some, this place probably makes perfect sense.

Buy this game if you like Legend Of Zelda dungeons, Portal maps or thinking.
Don't buy it if you don't like fun, challenges or insanity.

Reality is an illusion!
The world is a hologram!
Buy gold!

Oh, and say hi to the purple cube for me.
Infinite cubes!

The game opens with players spawning in a small, black room with a cartoon-style picture of a fetus on the wall. The first thing the player sees are these words: "Every journey is a series of choices. The first is to begin the journey." Players then turn to find a second wall labeled "All You Need to Know" that displays the options and the control scheme for the game, as well as a third wall labeled "Choose Your Destination" that acts as Antichamber's sort of level select feature. The map on this wall is initially only one room big, forcing players to select the very first room with only a vague idea of what this first "level" might hold for them.

From there Antichamber is very loosely organized, with players often being presented with multiple paths that lead to separate rooms on the map. Antichamber is often called a puzzle game, though its developers have more accurately labeled it a "mind-bending psychological exploration game". And in order to play Antichamber, your mind will have to bend—often into complex, pretzel-like contortions. The puzzle rooms of Antichamber frequently involve doing the opposite of what you expect. Each one requires creative thinking and the rooms often make up there own set of rules in order to solve them and then expect the player to figure each one out. Some rooms want you to walk quietly. Some rooms are shy and don't want you to look at them. Some rooms will only play fair if you walk backwards the whole time you're in them. Each puzzle is odd and unique, though I rarely found myself being frustrated. More often, I was enamored with their perturbingly unorthodox logic.

Should players grow irritated with a puzzle, however, a simple press of the ESC button will bring you straight back to where you started: the Main Hub. As you continue through the game, your map slowly expands into twisted corridors with labeled puzzle rooms listed on it, allowing you to transport yourself to any puzzle you've already encountered (though not always solved!). Along the way, players will often come upon black and white signs hanging on the walls in the hallways of Antichamber. The very first wall of the game, called the Moral Wall by fans, collects these signs, each one a black and white cartoon picture containing some sage words of advice when clicked.

The true beginning of Antichamber begins a handful of puzzle rooms in, when the player collects their very first Matter Gun, a weapon whose only ability is to collect and shoot out little colored cubes. There are five Matter Guns total, with each new gun being an upgrade from the last. Each one comes with its own set of abilities and rules that make more complex puzzles solvable, but in order to use the guns players are required to discover these abilities and rules with very little direction from the game itself. It's this lack of direction that makes Antichamber so clever: the game never tells you how a puzzle should be solved or even how to use most of the equipment it gives you to solve those puzzles. Players are required to pave their own way, developing and creating new techniques to tackle constantly changing challenges and sticky situations. Soon players end up with a large set of skills that have slowly been discovered through hours of trial and error.

Antichamber's journey has a quiet, unstated goal: there are no waypoints or quest lists to follow. Your only clue on where to go is the mysterious, flowing worm of black matter that appears early on in the game and the undeniable urge to delve deeper into the mysteries of Antichamber's hallways. However, a game like Antichamber does not need a strong sense of character or story. Antichamber places a higher value on gameplay and ingenuity than narrative, though the game is no less immersive because of it. In fact, Antichamber's atmosphere is enhanced by the silence of its white hallways and the player's fumbling, stumbling exploration of its convoluted structure.

People often believe Antichamber to be a sort of Portal clone—you're locked in an inescapable labyrinth, armed with a dubiously effective gun, and presented with a series of puzzles to solve. However, Antichamber is barely comparable to Portal. It is a more somber game, with a much less linear style of gameplay that is focused more on discovery and learning than the progression of a plot. You do not connect things, you create and destroy. You guess and postulate and trip and balk. There's no smooth sequences of flying through the air or near misses with laser beams or perfectly timed jumps. There's only a slow contemplation and the constant sensation of reaching into a dark hole and feeling your fingertips graze against something warm and smoky before it just slips away.

There are some games that I'm afraid to review. They're often games that, no matter how hard I try, I can't seem to find any noticeable flaws—games that I've become so pleased with that I would almost dare to call myself biased. Antichamber is one of those games that I've fallen in love with, a kind of unflinchingly blind sort of love that leaves me unable to see any of its faults. As such, it's no surprise that I'm giving it a positive review with the addition of a rarely ordered command: buy this game. Buy it now, and let yourself flounder in its often backwards and inside out logic.

I bought this game a long time ago, tried it for about thirty minutes, and then stopped. That was a mistake.


- Very abstract approach to puzzle solving, especially towards the beginning of the game. Makes you question everything, essentially.
- Mechanics work very well. Most of the details, including some very fine ones, are not revealed directly to you. You MUST experiment to work your way through this game.
- I like the design concept of the "main menu".
- The graphics are super simplistic (MSPaint simplistic), but I actually like that for this particular experience.

(Possible) Cons:

- The abstract puzzle solving! For the most part, I enjoyed exploring what I thought might be the solution to a puzzle and being wrong. There were a few times, though, when being right felt kind of dumb.
- I crashed the game about five times. Every time was due to one specific mechanic, wherein the game engine is evidently not designed to handle what I was doing to it.
- There is no real story and reaching the game's end is underwhelming. This game is 100% about puzzle solving and bending your ideas of "what should happen when I do X".

Not your normal puzzle game experience, but an enjoyable one all the same.

By age 2 most children fully understand object permanence, this is the first thing you need to start to unlearn with this game. The rules of this world is against most of what you've ever learned in life about how space should work.

Spoiler/Word of advice: If/When you get the filling mechanic, don't fill two opposing walls, the ceiling, and the floor up with blocks, it will crash the game as it tries to think about filling the room up with blocks,
