Does this work with Binding of Isaac : God Mode?
It is realy difficult to play in the catacombs because every obstacle are black !
I have the same problem. Sucks too because I love the mod otherwise. If / when this gets fixed I would love to reinstall the mod again.
You can fix it, open up the mod and go to the "gfx" section in "content" (it could also be in resources). Go in and delete every floor texture that isn't related to the septic floor.
can you do a rebirth version? pls
Small bug, In the catacombs, every wall and obstacle appears completely black , and it only happens there. The rest of the floors are fine.
for some reason the characters don't appear on the select screen and the items don't seem to be appearing, however the title screen has changed, plz help
Is this afterbirth+, afterbirth or rebirth? As for some reason afterbirth+ doesn't seem to work for me so I'm kinda stuck with afterbirth and well, I'm pretty bloody interested in trying this x3
Can i play this with other modpacks?
cool, but none of the items work and the drawn is too bugged
is this AB or AB+ cause i only have AB...
you automatically get ab+ if you have regular ab
cool , but the wiki is not complete
what does the read me say I cant open it
i dont get it, the wiki says that there many new bosses, but the sprites show only one, what happened with the others
This mod is can be used for original Afterbirth
Cous Afterbirth+ is not working for me...
