-Quick Review-
The Definition of Antichamber is “Brainteaser”. Antichamber is an indie puzzle game developed by Alexander Bruce (“Demruth”), Antichamber was released 2013 and is an excellent puzzle game that you should get right now.

-Detailed breakdown review-
Story: To my understanding there really isn't a “story”, not in the literal sense. You start the game working your way through puzzle after puzzle trying to get to the exit. There is a strong sense of progression and rewards for completing various puzzles, so in a way that's the story driving you... completing the puzzles and getting to the end.

Gameplay: The controls are very straightforward, and the game explains how to play as you play... Unless you miss one of the hints like I did once I got the yellow gun. I had to wander around the game for hours before returning to the original place I picked up the gun and noticed the tutorial tip.
As you progress through the game you obtain a gun, then upgrade that gun to get a different unique ability that will help you solve new puzzles and sometimes make the old puzzles easier. Just like any good puzzle game, each puzzle is tougher then the last, and often times dynamically different.
This is probably one of the hardest puzzle games I've ever played, Antichamber forces you to think about puzzle games in a whole different way (“To think outside the box”), and after you've gotten used to thinking a certain way for one puzzle the next requires you to think of a solution a different way.
There were a number of times playing Antichamber I thought “Yeah! I broke that puzzle with my creative solution” only to find out that the game actually EXPECTED me to figure that solution out the way I did. Expect twisted solutions, creative planning, strategic thinking, and down right mind screwing.

Achievements: At the time that I'm writing this review, there aren't any achievements (07/23/15) but they could easily be added later with a patch. The game already has many goals and hidden pathways that you can find. Including added difficulty if you're trying to beat the game in a short time.

Price: Antichamber is priced at $19.99, as most people who have consistently read my reviews knows, I like to spend an hour playing a game for every dollar.
So far I've spent 6.3 hours in the game, but it has a high replay value because puzzle games are always easy to come back to play, even after beating them. (I forget solutions to the puzzles and go through the whole process again!)
All in all, this game is definitely worth it to me, because I've enjoyed the challenges and the puzzles I've figured out on my own. (Just saying, I haven't looked up any solutions, if I got stuck I would go to another puzzle in the game!)

Conclusion: To quickly recap: Story, Not applicable. Gameplay, excellent, challenging, exciting, confusing, winning. Achievements, Not Applicable at this time. Price, fair, better if you purchase it when on sale.
I recommend this game to people who enjoy puzzle games (especially difficult puzzle games) For those of you who have played Portal... think of some of the most twisted... crazy... test chambers you might play on Portal? This game is like that, almost the whole time. It's awesome.
I think this game deserves a play, and even if you're not fond of puzzle games, the developers are indie so they could definitely use the support!
As always, thanks for reading my review.

This isn't just a game. This is... is... is love! This is life!

It's hard to choose the words to describe it. Well, I would pick these: unique, original, remarkable, astounding, challenging, unearthly, intriguing, vivid, colors, headache.

For some people, it may be more appreciated along with an aspirin.
It may also cause deep thoughts, amazement and/or a slight frustration due one's being too stupid to solve its puzzles. Beware.

I am immensely grateful to the developers for allowing this masterpiece to exist. Really, thanks.

I've never had reason to write a review before.

You need this game. Consitently, from its first moment to its last, it engages your assumptions and expectations in a way that opened my eyes to the potiental of video games as a medium. Even through a relatively simple mechanic of interaction with the environment - i.e laying blcoks down and picking them up - it cultivates a very real sense of agency for the player.

The game is not linear at all, in fact most of my difficulties happened because I was trying to do some puzzles before I had the rescources to do them. The paths branch off in all directions, and there are multiple ways into nearly every room. Each puzzle teaches you specific aspects of the rules, with later puzzles and abilites building and expanding on those lessons. All of this happens in a place where the laws of physics and spacial reality do not apply. I've had lots of my friends try playing this game, its crazy to see how differently they approach things.

My favorite part of the game though is how you create the narrative for yourself. I felt like I was unraveling a crazy, Lost style conspiracy complete with mysterious "radical other."

Don't take my word for it, put a tab on your tounge, buy this game, and grow
