Someone once said "If the laws of physics no longer apply in the future, God help you."

That game is here.

God help me.

I love mindfsk games.
THIS is a gorgeous mindfsk puzzle game. You don't have to listen to boring dialouge or pay attention to what is going on in the story. You just do. WARNING: Not a linear game. This is not just a puzzle game. It is an ultra mind♥♥♥♥. Be prepared to ragequit. Worth every penny and second.

Antichamber is easy to dismiss as a Portal clone at first glance; it is a first person puzzle game wherein you move from chamber to chamber, equipped with a puzzle “gun” which interacts with your environment. But while Portal deals mostly in learning the rules of its mechanics and then adding complexity to those mechanics, Antichamber is a game which aims to subvert your expectations about how a puzzle should fundamentally work. It makes you question the unspoken rules that video games abide by. Frequently, it is simply brilliant and mind blowing, though occasionally it’s too obscure or random for its own good (especially in later parts of the game).

There’s no real story to speak of in Antichamber, but the entire experience is expertly accented in a very sterile atmosphere and minimal graphics. Sound design is also minimal, but well done. Certain audio cues can give you hints to where you are in the world, and the simple tick-tock of a clock can become a fixture of an entire portion of the game. It’s definitely a polished game which looks and feels nice.

Of course, the real meat of Antichamber is the puzzles, and it’s hard to say much about them without revealing part of what makes this game special. Suffice it to say that it is one of the most unique and creative games that I have ever played. Environments are frequently non-Euclidean in nature, and rely heavily on perspective or understanding the rules of the universe which Antichamber itself has defined.

There is inherent difficulty in designing that kind of puzzle; if you don’t abide necessarily by the rules of physics or perspective that we’ve come to rely on, puzzles can have arbitrarily hard solutions. For the most part, especially in early parts of the game, Antichamber does an excellent job of staying consistent and teaching you the ways of its mind-melting world.

But in the later hours, you are bound to run into situations where a puzzle solution will feel almost entirely arbitrary. Frustration will set in, and occasionally solutions don’t have the satisfying payoff they were designed for. There was one instance where I resorted to some online hints because, it turns out, I had completed an earlier puzzle in a non-traditional way and didn’t have the resources the game expected me to have. It took quite a bit of digging before finally understanding how I was supposed to complete the prior puzzle so I could complete the current one.

One very smart addition to curb some of this difficulty is the ability to, at any point, press escape and jump out to the central hub of the world. From there, you can see your progress and also a map of the entire area you have so-far discovered. You can jump in to any area you’ve previously visited, and I found it helpful to jump from puzzle to puzzle I didn’t know how to solve. Typically inspiration would strike somewhere, and my frustrations would yield relatively quickly.

Overall, Antichamber is a smart, mostly incredible puzzle game. Moments of frustration are almost inevitable here, and for the most part the balance is hit just right so that frustration results in joyous satisfaction when you make progress. It occasionally missteps and frustration just leads to greater frustration, but it’s easy to forgive when so much of the game is so good. Highly recommended.

This game is totally awesome and crazy :D First it'll feel a little like Valves Portal but I assure you it's only at the beginning. Some philosphy elements and a bunch of skullcracking puzzles will entertain you for a couple or more of hours! Worth every cent of investment =)

Just play this game. It is that good. Some puzzles are tedious as hell, but it is worth playing through to the end. Most puzzle consist of switch activating and others consist of physics that are consistently non sensical, and this is its strong point. I would recommend that everyone try play this. Even if they don't play video games.

Clever puzzle game revolving around the use of perspective and non-Euclidean space in a minimalist environment. Puzzles were challenging without ever really feeling unfair (except for one instance: but it turned out to be an optional puzzle so i don't feel like I missed very much.) Great fun for anyone that loves the puzzle genre and can handle the potential headaches of navigating things that don't quite make sense, unless you force it to.

Things that annoyed me: There are a few precise platforming moments that feel awkward in the FPS scheme, and there was one puzzle that relied on an annoying jumping mechanic where I knew how to solve it but couldn't make the stiff platforming work 'properly' for lack of a better word.

Everything else was fantastic. I beat the game and I still have some puzzles left unsolved. Some of them seem to lead to hidden side areas that only exist for the satisfaction of getting there.

Like modern enigmas ? This is for you ! This game is brilliant, the gamplay is made to be absolutely with the main thing about the game, and having a gameplay coordinate to the main idea of a game, it's not that simple for a game based on enigmas and solving puzzle... Definitely a really good job, even if you're not good with that kind of game, this one is a perfect harmony of gameplay and puzzles AND without being boring ! There's always a kind of mystery thing that you absolutely want to discover, just wrtitting this makes me want to play it again !

I do not like puzzle games normally, but this game kept my interest. I'm sure that if you enjoy playing puzzle games and like having your mind stretched like a rubber band then this game is for you. Be prepared to think differently than you normally do.

One of my abosolute favorites. I will forever recommend this to other gamers as this game brought me HOURS of gameplay. Not only is it a game, its a piece of artwork, more clever than any game I have played in my life. I love it. Absolutely love it. It took me over a year, after many attempts, to finally beat it without looking anything up. I love the game producer and I hope you make more games like it.

One of my favorite games on steam. This game made me believe that anything is possible in a videogame. The trippy ways that they bend reality blew my mind. I also love the super atmospheric soundtrack.

Ran in circles in a locked room until I was sufficiently frustrated there was no exit. Walked the opposite direction and an exit appeared. Played for an hour, couldn't figure out how to progress forward, felt nauseous. Never went back. 8/10
