Insanely addictive

This game is highly addictive and has a lot of replay value. The game has plenty of unique boss battles and items that make the game even more addictive and fun. Plus every new game has randomly generated maps and enemies, making each playthrough different and unique. This may be the greatest indie game I've ever played and would highly recommend it, especially for the price.

This game is terrifying, thought provoking truly superb. For what it is, it may be perfect. No game has ever had this much replay-ability so it is the bargain of the century!


Beware the addiction

So this is one of the first games I ever got on steam...I had seen it previously but never really read into it...I just new it was a dark, zelda-esque dungeon game. It sounded a bit interesting so when I saw it on sale I figured I'd give it a shot....Dear lord how addictive I've come to find it to be....After many hours I still found the game refreshing and new each time. But had the desire to upgrade to Rebirth. Rebirth being the same game but with much, much more, and new design I've spent even more time. The game is as hard as it is fun...There are so many enemies and items that can screw you in an instant. So enjoy playing, just don't get to the point you want to rip your controller/keyboard in half


Quite Good, If Disturbing

The Binding of Isaac is one of those games that, if it's described, it doesn't really sound like it would work well. But yet, it does. The graphics are stylized, and while they can be a bit glitchy, they look fairly nice. Since YOU are most often the easiest thing to see on the screen, most hits feel kinda fair, though Hitboxes often don't match what they should due to Limitations of the engine. (This was fixed in the remake.) The gameplay is simple, and fun. Just keep going through floors in a manner very reminiscent of Zelda, killing enemies, unlocking doors, buying items in the shop and out of golden rooms. And really, the items make this game. There are so many synergies that for the most part, you'll never end two runs the same way. The soundtrack is fantastic. It's very fitting for the game, and manages to be both action packed, and suspenseful. Overall, while the remake may be better, the original BOI is still worth playing. I'd recommend grabbing it if you see it on sale.


Really good, but held back by technical limitations

uncleshelby | June 6, 2015 | See all uncleshelby's reviews »

The Binding of Isaac is a fantastic game with a lot of depth and hours upon hours of replayability. It's really an interesting game, but there is one thing that holds the entire game back: The game is a flash game, which limits the framerate to 30 FPS, which can easily drop below that, even on powerful computers. It also limits the amount of content and interesting things that can be done. Item synergies, min-maxing, etc. Fortunately, these are all solved in the sequel/reboot, The Binding of Isaac: Rebirth.
