Attention!: This is a DEMO!, it features 2 of the 8 levels in The Binding of ISaac.

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.

Decent, but is it ethical?

Is it really ethical to expect people to pay for procedurally generated content? I still haven't paid for the full version of Powder, yet, because frankly I don't relish the thought of spending money on a game that's not always possible to win.

Or, in the case of your game, spending money just to lock away content behind the randomizer. Why wouldn't I just rather enjoy and laugh at all the silly art and symbolism all in one swoop? Why purposefully frustrate myself in having to play numerous times just to catch that one, pesky little item that is staying hidden in some specific seed somewhere?

And there's another thing: how many possible variations on the world do you promise? I.e. how wide is the seed you're using? Am I going to see the same world twice, ever?

And one last thing: is it available for my iPod touch? The only way I'm going to pay for a little appy-game right now is if it's for my iPod touch.

People find this review helpful!

Not my cup of tea, but still this has impressed me

Even though it is not my cup of tea, I liked it. It is dark, disturbing and interesting enough to make me finish the demo even though it is hard as hell, but I like hard games so that is a plus. Great artwork and music is stunning. Don't have much else to say. Simple put it is a game worth buying :)

Great game

this game is awesome and people who think its gay that you have to pay for flash games, it doesent matter with what you make it, if its fun you should buy it.
its a great game.
and the game is only $5!
your complaining about one of the best flash games out there being $5?!
BTW, if every game was free, they couldnt make any more games and would go bankrupt and die cause of you being a greedy bastard.
apriciate that Edmin McMillen made this game instead of going on vacaction you greedy bastards
he could as well not have made a demo too.

Awesome but...

The demo is great,but I absoutely hate buying flashes when better ones are for free.No offense,but would you like it if you had to buy Pico's School or Telemite for $20?And,I have a thing against Steam because I wanted Garry's Mod,but it had to have extra items.(I suggest you make a FREE Binding of Issac for all gamers to see.)
Unless you get a big contract deal from Sony,Nintendo,or Microsoft,I rather not pay for a decent flash game that COULD be free.End of that story.Anyway,I hope you get a lot of downloads.Tankattack,out.
