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.
Despite its performance issues, BoI is still the best bullet hell and roguelike I've ever played. It is so incredibly fun and so hard and so different every time. I can't wait for the non-Flash remake!!!
