This is pretty much a roguelike dungeon crawler with quite a bit of influences taken from Zelda, and a ton of religious/Satanic overtones and pretty taboo themes, which was probably designed for masochists.
...And I mean this in the best way possible.

+ Fun and rewarding combat
+ The game is difficult, but also fair towards the player
+ Nice cutesy but brutal art style
+ Gameplay is random with its roguelike elements, making it very addictive
+ A lot of different items and powerups to mess around with
+ Multiple unlockable characters to suit multiple playstyles
+ Plot has a ton of social commentary that will hopefully leave you thinking even after you stop playing

- Can be glitchy at times
- Difficulty curve can be very brutal for newcomers

? If you're a pretty religious person, you may be pretty offended by the game's style, plot, messages and humor, but you may be able to overlook these things.

Overall, I would totally recommend this game to other people.

Where do I start? This game is extremely frustrating to get the hang of. Unless you are a god, you probably can't beat it the first time you play. It took me 42 attempts to beat all six floors and Mom for the first time.
I guarantee you will lose your temper at this game at some point.
And you might have to do a bit of research on the Wiki or experimenting in-game to find out what every single trinket, activated item, passives and tarot card does and which ones are good or bad for every unlockable character.
You might have to take your chances with the pills, as each type is randomly paired with an ability during each run.


The Binding of Isaac is not, and I repeat, NOT, a bad game. As much as it is frustrating, it is really addictive. I thoroughly recommend this to fans of dungeon-styled and bullet hell games. Despite Isaac's innocent look (which he kinda is...look at those big crying eyes!), the style of enemies, rooms and pickups can be incredibly morbid and disturbing. The cries of Mulligans and the appearance of Hives are incredibly distressing, adding to the games overall atmosphere. Nonetheless this really adds charm to the game as a whole. Bear in mind this is coming from the creators of Super Meat Boy, so expect some blood along the way. But what's fun is you never know what to expect. All of the dungeon floor layouts are randomly generated everytime you start a game and aside from Mom being the last boss in the Depths, you never know what boss you will get upon entering its room. There are set bosses for every floor type and the game will randomly select one of these for you to battle. There is a sense of mystery about this game, mainly regarding the bosses, items you can find and what each pill does in every run.

Now stop reading this and go buy The Binding of Isaac!!

After more than 700 hours I think it's finally time to review this game, since I think I have played a good amount to give my unbiased oppinino on The Binding of Isaac.

First and foremost: Yes, I have played Rebirth. I think it was around my 500 hour mark when Rebirth was released and I was hyped like everyone else but my interest for Rebirth died down really fast and I continued playing Classic Isaac (for a more detailed review on why I prefer Classic Isaac over Rebirth, feel free to check my Review for Rebirth.)

However, I absolutely love this game. I would even go so far and say that it's the absolute best game I have ever played and I started playing games when I had a SNES, so calling a game that was made in flash my favorite game of all time is a huge accomplishment.

The skill cap in this game is something that is insanely good, games where you can feel that you get progressively better are very rare to come across, but the more you play it, the more you learn what which items do how you can get the most out of every single floor and of course dodging, the more you play it, the better you get at it.

The cool thing is, that even after 700 hours you might not find any more secrets or anything like that, but the game never feels repetitive, since every run has a different layout of floors, the items you find are different, the bosses you find are different and the drops you find, as well.

Also what this game has over Rebirth, in my opinion, is the limited amount of Items.
Sure, there are people who say that at some point u just get specific items and just restart a run to the point where you get an item that is useful, so you limit yourself to a certain amount of items. But that's all up to oneself. You can either restart all time until you get your desired item, but you can also start off with a really bad item and get god-tier items along the way. The way how you play a run with a bad item and how you eventually make it work is all up to your skill at the long run.
What I was trying to say is, there are less items in Classic Isaac than in Rebirth, so ultimately you have more control and it is more likely that you get an item that you actually like. As I said, some might see that as a negative, since you limit yourself to certain items, but if I play 20+ runs and only get 1 run where I get 1 item that I like, that's no fun to me.

All in all The Binding of Isaac is my favorite game of all time, I would even say the benchmark for all Rogue-like games.

(Eternal Edition) As far as the eternal edition go (which is an update for Isaac that was released a couple of days ago) I totally enjoy this update. It adds a Hard Mode to the gae, so for people who have played this game for 700+ hours and don't wanna switch over to Rebirth, this is a great addition, because the name "Hard Mode" is exactly what it says.

There are "eternal forms" of regular mobs and bosses who are way tougher to beat. They have more hit points and different attacks. Another thing that they fixed, which they also added for the regular version, is the time you freeze whenever you pick up an item, trinket, pill, tarot- or playing card. The frame in which you freeze and can't move has been reduced which makes it easier for you to dodge enemies.
Once the bugs have been ironed out (there is currently a bug where you can't get out of a room when you fight the eternal form of "Loki" this update will be even more awesome than it already is.

As I said, if you love Rogue-likes, chances are that you already have this game, but if not, you should definitely give this game a try.

I already have 700+ hours in this game and I plan to invest more hours in the future. This game never gets old.
