About the game:

When Isaac's mother starts hearing the voice of God demanding a sacrifice be made to prove her faith, Isaac escapes into the basement facing droves of deranged enemies, lost brothers and sisters, his fears, and eventually his mother.

The Binding of Isaac is a randomly generated action RPG shooter with heavy Rogue-like elements. Following Isaac on his journey players will find bizarre treasures that change Isaac's form giving him super human abilities and enabling him to fight off droves of mysterious creatures, discover secrets and fight his way to safety.

Cool game, great feel.

I actually have the game already, but for some reason it fills me with a certain measure of joy to see you put some part of it on Newgrounds. It just feels like it is part of this site, for some reason. Anyway, I've had a lot of fun playing the game- some of the upgrades are pretty creative, and there's an interesting atmosphere to it.

Almost Perfect

I love the mood and feel of this game. Everything is great except for the controls... they feel clunky. Collision control is weird too... sometimes you take a hit when you pass by an object without really touching it.

If the controls were tightened up... I could see buying the full version. Cool idea!

At first I thought the game was gonna be too easy and I was worried. Had team meat gone soft? I said! But no level 2 chewed me up and spit me out. Awesome demo I'm going to buy it for sure now.

Excellent game....but really disturbing.

I absolutely love the graphics and the music mostly because they are reminiscent of Meat Boy! It feels a lot like Zelda at times which is awesome. The intro is really well done. The only downfall for me was the fact that it was really disturbing, and even though it was freaky, I can overlook that small fact because the gameplay is good. Well done once again Mr. McMillen I love your games! As for the sounds and music I loved both, I'm a huge fan of Danny Baranowsky's music and the sounds were great. Great job!

Lol Isaac from the Bible?

Is that Isaac from the bible but modern? Because it was he who was supposed to be sacrificed but Abraham chose not to. And no I am not a nerd at Christianity.
