Click for Gameplay Trailer - Review
Players control young protagonist Isaac, escaping his fanatically Christian mother. Upon hearing sacred words from the Lord, she attempts to play Abraham and sacrifice her son for the greater good. Escaping through his home's scary basement, Isaac has only his many tears to defend himself against not only his mother, but legions of creepy-crawlies and some other genuinely disturbing monsters.

Gross humor and questionable setting aside, The Binding of Isaac still has a certain graphical charm. You’ll notice the fluidity of animation more than anything else, though the actual environments are still well-done – a cut above the Super Nintendo Zelda era the game very consciously tries to spoof.

Speaking of audio, the game has very good music for setting the mood. The sound effects are passable, with some of the sounds of the tormented child-monsters being appropriately disturbing.

Each visit to The Binding of Isaac develops organically into a distinctive experience. The game possesses a huge array of weapons, power-ups, monsters, mini-bosses, treasures, and traps. Even if you conquer all of the dungeons on a given playthrough, you'll only see a fraction of the possibilities.
The power-ups that affect said tears come in many forms, want to cry faster? Pick up the Sad Onion. Want to cry harder? Pick up a dead puppy's head. Want to cry farther? Why, pick up Mom's Lipstick, her Underwear, or her Heels.
You have flies orbiting you and protect you from most projectiles and trusty meatboy running around the room and eating your enemies while you cower in fear in a corner, or you run around black as hell itself with your psychic powers guiding your hunka big ♥♥♥ tears right into your enemies with a poop on your head so all them unfriendly flies love you.

Isaac's only given three hearts-worth of life to begin with and once that's gone, it's game over; you lose all your progress and have to start over again without health upgrades, weapons or collectibles. Perma-death adds suspense and randomly-generated content provides a lot of replayability. On the other hand, the fact that your potential for beating the game is ultimately dependent on the luck of the draw can be more than a little frustrating. I beat the game only once in 4 hours. YES im very bad :)

This is one of those games which is easy to learn, yet hard to master!
The Binding of Isaa is so cleverly designed and so deliciously replayable that I cant stop to play. i love it!

Sorry for my bad english. This is my review account, because the low playtime.
Thanks for reading! If you Like my Review, give me a Thumbs up in Steam.
Your help is greatly appreciated :)

What can I say about The Binding of Isaac. This is by far the best indie games of 2011 I have played. Old school NES Fans, you will not be disappointed. This game has a somewhat resemblance to The Legend of Zelda's dungeons. Even newer gamers will appreciate this addicting, simple yet complex Rogue-Shooter. Coming from the makers of Super Meat Boy, this is a sad comedic gore fest full of surprises. Note that You will die a lot at first but as you keep playing, there are a lot of things to unlock and discover. This game's price value is also a must get for your steam game collection. At 4,99€ you can't go wrong no matter what. Dungeons filled with disgusting and gory, yet funny and sad enemies, will leave you wanting more and more. I found myself a lot of times putting other games aside to go play this game. I will end this review short and simple.

A little game with some really good working dark humor. It's very difficult but that's what makes it lasts for soo long. Very addictive game with a high replay rate.

Few games can truly claim to walk the fine line between fun and frustration as much as The Binding of Isaac, another hellishly difficult title from Edmund McMillen: the man behind Super Meat Boy. It’s a title that delights in pushing players to the point where they want to start taking swings at their computer before attempting another round guiding its titular tyke through a series of nightmarish and randomized dungeons.

A brief animated intro sets up the threadbare plot: Isaac is a young boy living a happy life at home with his mom until she starts hearing the voice of God and hiding him from the evils of the world. It isn’t long until Isaac is permanently locked in his room and awaiting execution at the hands of his mother at the almighty’s behest. Escaping into the basement, Isaac begins his bizarre journey.

The Binding of Isaac somehow manages to be disturbing as it is endearing with its balance of gruesome monsters and matching setting with its adorable, wide-eyed sprites. Dungeons are splashed in every foul bodily fluid imaginable—blood, guts, tears, urine, and even an uncomfortable amount of feces. Imagine Hellraiser filmed through the lens of a Saturday morning cartoon for kids. The bestiary is equally grotesque. Armies of maggots and flies are frequent foes, and headless children spewing fountains of blood from their necks are a common sight.

Bosses take things a distasteful step forward: fetuses, conjoined twins, fat slugs urinating on the floor, and even Isaac’s mother are just a few of the end-level bosses that need to be dealt with. Keep in mind that the protagonist is also a perpetually-naked boy using his tears as projectiles. The Binding of Isaac is a pretty sick game with aesthetics that would appeal to one’s inner horror fan and Splatterhouse enthusiast. It isn’t going to be to everyone’s tastes, but those that enjoyed Super Meat Boy are probably going to find themselves like McMillen’s perverted sense of style.

Since the dungeons are randomized, there’s no telling what you’re going to find whether it be a useful power-up or more monsters. This makes memorization of each level impossible and keeps the experience fresh every time. On the downside, this means success depends on good luck and players will often lose because they were dealt a bad hand. Every time Isaac dies, players wind up right back at the start of the game and even the most patient of individuals will become infuriated by such a design choice. After putting in so much effort and acquiring a myriad of useful abilities, it feels way too harsh.

The randomness extends to the power-ups themselves, as there are well over a hundred of them and they don’t always have the expected effect. Some even hurt Isaac and if used in a tight spot are going to guarantee death. At the very least, they can be used in conjunction with other power ups and there’s not much of a limit on how many of them can be used at the same time. Still, there’s nothing worse than getting bad power-ups and items with no end in sight. At that point, it’s probably best to just quit and start again.

There’s even some replayability to the title with extra characters that can be unlocked and a bit of exploring to see if there’s anything particularly useful in a given dungeon. The Binding of Isaac is a purposefully short title designed to be played many times over, not just due to its unforgiving nature, that will yield a surprise here and there when players think they’re seen everything. Its ability to keep you guessing is its greatest strength and weakness as it violently seesaws between an enjoyable 2D romp and unbridled frustration.

The Binding of Isaac is not for those that are easily deterred, and it’s a safe bet that any Super Meat Boy fans are going to sink their teeth into it. For such a small title, there’s a lot of content packed into it and it’s an experience that isn’t always the same from one playthrough to the next. Players will question whether it was their own skill that carried them through to the end or if it was sheer luck, but regardless of the difficulty it’s an approachable game with a unique charm that boils blood just as easily as it encourages laughter at Isaac’s cartoonish spectacle of childhood trauma.

10/10 - MUST PLAY - Highly Recommended

This game is right up my alley. Love the music, atmosphere, and the writing/vibe the game gives you. I don't binge on this game as well I kinda suck at it lol. With that said I love this game and I am looking forward to the updated version coming out soon. Also if you are on PS4 the month of november 2014 I believe they are giving BOI Rebirth for free to all who have the online activated. Anways if you love to kill things that are creepy and morbid this is your game. 10/10

17 hours of my life playing this simple frustrating game.
Pros- Cheap, Rooms are random so, no 2 games are the same, you don't require huge specs to run this game. It's also very tiny in file size.
Cons- Collectables don't say what they do so when you use them, they can be (usually are) wasted.
It's handy to have a cheat sheet open in your browser that says what each item does.


EDIT: The trailer is messed up as ♥♥♥♥ - 11/10

After 108 hours I finally 100% completed The Binding of Isaac + Wrath of the Lamb expansion (all 84 achievements).
The amount of hours you can put into it until you don't have nothing else to do is simply incredible given the price you can pay for the pack with the game and expansion (0.99 on a sale).

If you never played the game before expect to finish it completely in 150-200+ hours (depending on your skill in this kind of game).

For new players the game will probably be kinda difficult and even more with the expansion content so i would recommend playing without it installed (under DLC tab in game properties) at least until you have unlocked It Lives or beaten Sheol once.
After that you'll be able to handle most of the new enemies and bosses, and you will appreciate the addition of trinkets and new items.

There are several drawbacks with the expansion. Mostly glitches that it introduces such as enemies glitching through some corners, not properly working Brimstone controls, etc. but with all the new game elements you can easily forget about this.

PS. Gorgeous soundtrack if you don't know it yet.


Despues de 108 horas al fin he completado al 100% The Binding of Isaac + la expansion Wrath of the Lamb (los 84 logros).
La cantidad de horas que puedes echarle hasta que no tienes nada mas que hacer es simplemente increible dado el precio por el que puedes comprar el pack con el juego y la expansion (0.99 rebajado).

Si nunca has jugado al juego puedes esperar acabarlo completamente en mas de 150-200 horas (dependiendo de tu habilidad en este tipo de juego).

A los nuevos jugadores probablemente les resulte dificil y mas aun con el contenido de la expansion, asi que recomendaria jugar sin ella instalada (en la pestaña DLC de las propiedades del juego) al menos hasta que hayas desbloqueado It Lives o superado Sheol una vez. Despues de eso estaras preparado para los nuevos enemigos y jefes, y apreciaras mas los nuevos objetos y los trinkets.

La expansion tiene algunos inconvenientes como glitches que introduce del tipo enemigos que traspasan algunas esquinas, los controles del objeto Brimstone no funcionan muy bien, etc. pero con la cantidad de nuevos elementos en el juego uno se puede olvidar perfectamente de esto.

PD. Si todavia no lo sabes la banda sonora es impresionante.

9.5/10.One of the best games I have played in a while.Great idea.Great developers.Everything in this game is simply amazing.The game has a lot of replayability,its cheap,it runs on almost every computer,no need for you to have those fancy Titans or anything.The only reason this is not a 10/10 is because the game runs on Flash player,which GREATLY limits the things this game is capable of.
If you like Rogue-like indie games and you don't want to spend a lot of money,this is the game for you.
Although I would strongly suggest waiting a week or so for The Binding of Isaac:Rebirth.A little more expencive but totally worth every single cent.
