Bugs:The Binding of Isaac
This page details bugs of The Binding of Isaac.
??? Before Unlock
If you die with the Ankh item and respawn as ???, you can hold R to do a new run as ???, even before unlocking him.
Note: A mod known as SpiderMod is being used to give the item at will. The mod is not affecting anything else.
Brimsnap
Firing a laser with the Brimstone item, then repeatedly tapping the same key in the direction you fired allows you to deal additional damage. This also as a result, makes Isaac appear as if he is firing the Brimstone laser towards the bottom of the screen, although the laser is still being fired in the direction you fired.
This bug has been dubbed the Brimsnap by the community.
Note (again): A mod known as SpiderMod is being used to give the item at will. The mod is not affecting anything else.
Ipecac Double Explosion
If you use the Remote Detonator after launching a projectile with IPECAC it will cause a second explosion in the same location.
