Antichamber is definitely one of the best puzzle games I've played. It's a very unique experience that plays with your perception and makes you think outside the box. It has a very bright color pallet that helps point out specific points of interest (although it can strain your eyes after a while), and it has some very interesting uses of ambient sounds. As you progress, you will find images on the walls that, when clicked on, will give you quotes about life experiences while also acting as hints on how to solve the next puzzle. On my first playthrough, I was completely lost in barely the first quarter of the game, mainly because I didn't realize that there are mechanics to this game that can be applied elsewhere. I returned about 1 or 2 years later, and beat it in one day, slowly remembering some of the things I did wrong the last time I played. The game may be daunting at first, but it's much more possible than you may think.

Another great thing about this game is that I can't recall a single puzzle in here that I would dread to do again on repeat playthroughs. In most puzzle games there's usually that one puzzle that you absolutely hate to do and you typically stop playing there. Even if you know the solution, it's so frustrating and uninteresting that you loose the motivation to continue playing. The most annoying puzzle in this game wasn't all that annoying once I figured it out, it only took me about 10 minutes and it was optional. It just unlocked a special room that was not required to beat the game, it was simply a nice bonus room.

I do have some tips to save first-time players from unnecessary agony:
  • Remember every game mechanic the game shows you, they aren't just one-time gimmicks.
In the beginning, the game will throw a lot of new mechanics at you one at a time, which made me think they were all one-time gimmicks. I eventually became stuck for a while because I didn't realize I had to use one of the mechanics from earlier. I restarted my save file, was re-introduced to that mechanic, and finally realized what I did wrong. Just make sure you remember every mechanic the game shows you, no matter how insignificant it may seem at the time.
  • Most rooms and interactable cubes are color-coded. If your current or any previous guns do not match the color of the cubes, you probably can't solve that puzzle yet.
This is an issue caused by the non-linearity of the game. Often when I encountered a new puzzle, I was never too sure if I couldn't complete it because I was missing a tool or ability, or if I was just not seeing the answer. To prevent this from happening, just keep in mind that most puzzles that involve interactable cubes (the kind you can pick-up and place) are color coded to match the color gun upgrade you need to solve that puzzle. I don't want to spoil much, but you'll understand once you're further into the game.
  • You can never quite get your bearings.
The non-linearity of this game also creates a problem with your spatial-awareness. The game has so many twists and turns, and some areas and paths are different depending on you current actions. This becomes very disorienting, and there is practically no logical way to map the game out in your head. There is a map in the game, but it's mainly used as a fast-travel system and to give you hints on where to look next. The layout does not actually make much sense. You kind of just have to keep wandering around trying the different paths until you get somewhere new.

Finally, some personal gripes about the game. There are a couple of "dead ends" in the game, they're puzzles or rooms that seem to exist for no reason. It left me a bit confused as to whether they were put there intentionally to add to the feel of Antichamber's universe, or if the developers actually forgot to remove/finish it. There's even a door that is labeled "Under Construction". There are also pink cubes scattered throughout the game. I was really interested in these, as they seemed to be some kind of collectible. Upon further research, they were actually supposed to be collectibles, but the feature was never fully implemented. Nothing ever happens when you collect them all, and there are even some that are completely unobtainable.

Aside from it's flaws, this is definitely a game that should be experienced at least once in your lifetime, and is a remarkable technological feat.

A Short and sweet Puzzle game with a 'Trippy' aesthetic, Antichamber is an enjoyable adventure from start to finish.

In here, you'll go around completing puzzles and obtaining a Portal Gun-esque tool and it's upgrades that will allow you to modify, multiply, and remove small colored cubes to progress, all while trying to beat the clock.

That´s particulary amazing. Even though I got this as a gift, I would have paid the full price. I should have got this way earlier, but I didn´t know if it was worth it. It is.

When you are playing this your first time you may be confused, you will wonder what kind of game this is. But if you are getting started, this becomes more and more interesting. Who said a game needs to look realistic? This is the proof that isn´t the case at all. Antichamber looks amazing, but yet UNREAL (got it?). You are wondering what that "Antichamber" is, while you are trying to suceed. There isn´t much explanation needed, it´s easy to progress by trial and error and you still don´t get upset. I really enjoyed the design, as weird as it is, and I always managed to play on. There are also a lot of hidden hints, all over the map, which is enourmous. Later you can even unlock some helpful abilities while you´re trying to find out what´s going on.

If you doubt like I did, don´t wait to buy it. If you like Puzzles, you will love this!

I’d sum up Antichamber as an illogical, logical puzzle game. I had to think more abstract and “outside the box” than any other puzzle game I’ve played before. It’s frustrating, rewarding and beautiful in a minimalist way. All of which comes together as a fantastic game.

You’re immediately thrown into the game. No menu, just instant gameplay. Great for quick 10-20 minutes sessions but also has the ability to eat up hours while you try to get past a seemingly impossible puzzle.

The first thing you’ll notice are the visuals. It’s minimalistic and heavily based on lines and outlines with vibrant colors. It’s beautiful and unique but also doubles a way to easily draw your eye to important things.

Music and sounds are also good. The background music is always there but never got in the way and I never got tired of it. In fact, I typically wouldn’t even hear it since I was concentrating on a puzzle.

Gameplay is going to be a tough one to write about, so I’ll be as brief as I can. There is no traditional story and I think the hints you gather along the way form a story about life and questioning yourself. You must make your way through various puzzle rooms. The main room, which you can exit to at any time, serves as a map and to show your progress with the “hints” you have gotten along the way. The hints are posters you’ll see on the walls and serve as cryptic messages or meanings to solve the puzzle. Most of them have you contemplating your own life decisions, haha. You will eventually collect 3 guns that allow you to manipulate, store and shoot cubes to solve puzzles. Each gun will allow you to do a little bit more with the cubes, letting you get past puzzles you may have been stuck on before.

Antichamber is difficult, but only because it’s difficult to think and twist your mind in order to come up with a solution. I’ll admit I looked at a guide more than a handful of times. It’s frustrating in the beginning because you are not accustomed to the style of puzzles but eventually you start to always think outside the box. Looking back, it’s pretty funny how much you change your thinking from beginning to end.

+Unique and beautiful visuals
+Unique gameplay
+Changes how you problem solve
+Hint system has you questioning life

+Frustrating at times
+Better anti-aliasing solution could be used

8/10 Very good

Not a game for all. But the level of mind-blowingness and the out-of-the-box way of thinking that you'll need will be pure joy for your brain. If you like to be surprised and yell "WTF!?" at the screen at every corner this is the game for you. Brilliantly designed, clever, original, and fun.

A short 1.5-3 hour puzzle game done so well that it's rarely, if ever more frustrating than it is interesting.

Having access to the primary hub at any time ensures that you never get stuck, and that you can reset whenever you feel like it, and that you can also make your way to other areas when you learn or acquire something new.

Antichamber takes a self-help/lifeadvice approach to teaching and then applies the lessons to puzzles as a sort of hint. The entire experience is consistantly gratifying and fulfilling. Of all of the interesting and occasionally confusing puzzles there are really only about 2-3 elements of the game that present themselves as truley frustrating, but not particularly difficult.

The best thing about the game is that you really feel like you've learned how to get around things by the end of it all, particularly because you're not required to think one specific way; antichamber is a game where you can often see the solution and then determine a way to get there, there's hardly ever just one single way to do things, and the game doesn't really mind if you outsmart it. It's fantastic to be able to finese your way through some puzzles while brute-forcing through others when it feels right.

I'm not normally one to play through a game more than once if necessary, but I have no doubt that I'll come back to Antichamber.

This is likely the best puzzle game I've ever played, perfectly toeing the line between being esoteric and intuitive. Each new puzzle feels utterly impossible, until something clicks, and then it's suddenly laughably easy. No other game I've played managed to capture such a contrast without feeling contrived or frusterating, but this one has. With its "story" conveyed by little tiles on the wall, and its interface never once showing you a menu in a conventional sense, this game managed to be immersive in the face of a massively surreal environment, leading me to feel as though I was actually in this odd place. Given the nature of the setting, this was utterly shocking. This game is not so much a game as a work of art in the interactive medium.

I cannot recommend this game enough.

Put probably around eight total hours into the game, (Don't mind whatever is above that eight hours, because I was AFK for anything past that) and I have to tell you, I've never had very many games give me goosebumps at the puzzles and themes that develop in Antichamber.

A fantastic puzzle game, and a real brain tease. This is a game anyone should play if they're looking for a challenge.

Antichamber is a really enjoyable puzzle game. The difficulty and game length felt right, and the puzzles' basis in illusion felt unique and interesting without being overwhelming. You don't need an understanding of some higher order math to finish this game, but it is still satisfyingly challenging. I appreciated that if I ever was stumped by a puzzle, it didn't usually mean I was *stuck*, because at any time there were usually several puzzles available in other areas that I could switch over to solve.

The game also has a cool atmosphere supported by its minimalist visuals and ambient music/sound. I especially loved the harmonic, electrical hum that your gun has while using it. Any story is left to implication, so doesn't interfere with the game play at all.

Definitely worth playing.

One of the best games I've ever played. I regularly hope for more like it. It is snarky and mind-bendy in exactly the way most puzzle/adventure games ought to be. The ending isn't mind-blowing (unless I've missed something, and I probably have), but getting there is definitely an achievement, and I enjoyed every silly pictogram.
