Simple yet complex.

It's rated mature in Germany for a reason; it's blasphemous but unless you're isaacs mom you won't be offended, it's perma-death so every heart counts adding difficulty, and the dark humor the game exhibits make it humorous when a crying child picks up absurd things from his mom and wears them to somehow get perks for his eternal tears

If you like a challenge this is the game for you. I have fully completed this game and I must say it can be pretty rage inducing at some points and luck determines a main part of how the game goes, but to win you do need to try pretty hard yourself too and overal the game is pretty balanced. If you buy the game you should buy the Wrath of the Lamb DLC with it since it is really worth it. It includes more items and bosses.
There is a remake of the game called The binding of Isaac: Rebirth (And Afterbirth DLC) and if you like this game I would also recommend Rebirth since it's mostly the same game but with even more horrors and challenges. This game does have one major addition called hard mode/ ethernal mode which adds even harder bosses and harder variations on existing monsters.

In conclusion, the game is pretty hard and if you like a chalenge you should consider buying this game especially if its on sale.

Alright first things first Yes, i got a 100% save file cause i did not have the time to beat the game that much but i almost never play on it, do not witchhunt me.
Now for the real review

Alllright so heres why i havent played it much, First of all, LAGGY AF, for its hand drawn style(as shown in video) i expected it to not be to laggy, boy was i wrong, Not a bad game but sooo many things could be better.

As mentioned above, the hand drawn style is amazing, i love it. I love how creative the enemies and bosses are and besides the lag its not a bad game.

The amount of lag it has, sorry for metioning it twice but, really? how could you mess up such and amazing game by making it soooooo laggy?!!

Okay, 3rd and last time im gonna say it THE, LAG, its just, like why?!? i paid for this game, i want it to be able to run 40+ fps on a decent computer. last thing i would change, maybe add a few more bosses.

Overall review

Tbh i have to rate it a 8/10

(Ratings key{im out of things to write})

10/10: Amazing no complaints
9/10:Im impressed, Minor issues
8/10:Alright, im down, some pretty noticable issues but nothing to bad.
7/10:Pretty good, but could be better
6/10:I mean nothing terrible but could be alot better.
5/10 Pretty indeffirent about it, Didnt hate it, didnt like it,
4/10: (Paid for game:Not really good, but i would play it if i was bored.) (Free game: Eh, it was free so nothing wasted_
3/10, Okay, this isnt to good, enjoyable parts but... just no.
2/10 - 1/10 (Speechless.)
(one last thing, dont take this inaccurately just cause i have so little play time, i've seen alot of videos, this is my personal review on what i have seen.)

The Binding of Isaac, from here on BI in short, is a dungeon-styled game where the player has to master several dungeons to reach his goal (that's shown in form of a treasure chest). Many theories are roaming around the story of Isaac and there are some good ones, but you shall figure it out on your own.

By the time you reach a point in the story where you will get many different endings which does not really help clarify the situation of Isaac's story at all.
BI is a hard-to-learn but well-to-play game afterwards which makes it interesting. Just put some music on in the background and struggle through the life as Isaac or the many other characters.

If you want your mind blown cause plot twists, then play this game!

*Kills a Blood Thirsty Blob, Destroys the Unholy Reincarnataion of the Zodiac Gemini, Pees on his Mom until she dies, Throws a dead bird to kill all in his way, Dies by a Fly*

I swear the logic behind this game...

Really nice Indie game ! I think The Binding of Isaac is part of the best Indie games with Super Meat Boy and others.

At first, I found this game kinda horrific to be honest, but after a bit of time, I appreciated it, and now, I don't care to see a child kill misshapens childs with his tears.
I don't care to see a child kill its own mother heart.
I don't care to see a child kill Sat... What ?!

Yeah... this game helped me discover one of the best OST ever.

The gameplay is really simple, but the game itself is really hard when you use to play at the highest difficulties.

- 10 differents floor ( with DLC )
- The Basement
- The Cellar ( with DLC )
- The Caves
- The Catacombs ( with DLC )
- The Depths
- Necropolis ( with DLC )
- The Womb
- Utero ( with DLC )
- Cathedral
- Sheol
A looooooooooooooooooooooooooooooooot of differents ennemies, and a... AN INFINITE AMOUNT OF COMBINATION

You have 6846467486756415647 items, and you'll need luck to get the best of them to become a God...

Hmm... yeah.
8/10, because the DLC make me lag a lot.

One of my favorite games of all time now. Wow where do i even start? the gameplay is twinstick, which i like already, the rouge lite elements are cool, and changing isaac's appearance is fun, because of the random powerups, the difficulty is JUST right, not too hard, while at the same time just hard enough (to me anyway), the art is creepy, and intriguing and the graphical style is something i always end up enjoying.... don't get me started on the messed up story. do i recommend this game? yes Highly, and even the Binding of Isaac rebirth/Afterbirth (which i have for ps4) this game gets a 5/5

This is a great roguelike game totally ruined by the fact it uses Flash. No matter how fast your processor is, fps will drop. the controls will become less responsive, and you will not be able to dodge another projectile hurled at you or another monster trying to hit you. And, of course, fps will drop when there are many objects on the screen.

Buy The Binding of Isaac: Rebirth and Afterbirth instead. That game has a different engine with stable 60 fps and a ton more content.
