"One may play for an hour or two, but they're constantly tempted to go back in and uncover the scads of remaining secrets. It's a style of game that really intrigues me, and one I want to see more of" -

One of the best indie games

The Binding of Isaac is an indie, roguelike, action RPG shooter (talk about a mish mash of genres) with incredibly high replayability value and oozng with massive amounts of originality and ingenuity, not to mention various references to other games included. This game is not for the weak of heart. I personally consider it one of the most difficult games I've ever played, and that is saying a lot. Especially for completionists/achievement getters, TBoI can be a nightmare (of course, if you're good at this type of game, it might not be so bad; for the rest of us, be prepared to invest hundreds of hours and die countless times if you want to obtain everyhing the game has to offer; be aware that luck is a deciding factor alongside skill, since the levels are randomly generated, thus the high replayability value). For a very cheap price, this game is a must buy for any gamer with self respect. Those that want more of the Isaac experience can try the sequ.. err, pseudoremake Rebirth.


Incredibly addictive

This game is a fantastic, highly addictive dungeon-style game. The game goes through several floors where the player must clear a path to the boss(es) in order to go down to the next level. The games levels are randomly generated which can lead to very interesting item-pickups which can either ruin a run or make it much better. The music in this game is fantastic so I'd recommend buying the OST on iTunes as well. I'd also recommend picking up the sequel, BoI: Rebirth. Rebirth is good once you've become a veteran in the original as it can be much harder and implements many more items/enemies.


Awesome and addicting!

If you want to waste time that you could spend with people, then this is the perfect game for you. I've spent countless times playing it over and over, only to find myself back at the start playing again. The great thing about it is variation, the maps are randomly generated each time, and mystery pills are always exciting to use. Also, is it weird to describe some of the monsters as cute?


Different and fun

TBOI is one of the best indie games i've ever played, it shows good artwork and a new way to play a game without using guns, but with your tears.The game is roguelike and the levels are generated randomly, every run will be different from the last one, every level has a treasure room, with an item to help you manage to survive through the other harder levels, i've done 100% of the achievements on steam (before they added eternal ones) they are really difficult like the game,but when you get them you will feel awesome,a good choice if you can't spend soo much money and if you liked it download TBOI:rebirth.


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.
