This is one of the good ones dude
keep the good work up!
Can I still get the lost unlocks with the lamb?
for everyone who is having issues saying the lamb isnt showing up first do you have the lost because the description says the lamb replaces the lost second of all remove all the test documents from the file those are the README.txt rules.txt fortunes.txt and changelog.txt
im pretty sure the fortunes.txt are the fortunes you get from the machine....

for some reason the lamb isnt showing up
what version of isaac do you have?
do you mind if i use this in one of my mods? you will be credited
thanks BTW credits page in game or mod page
I need to know how you would like to be credited
Could you just put the link to my mod on the mod page
can you make a custom version where azazel is replaced Instead?
I can't play it. the game just keeps crashing when I play the game.
I don't have afterbirth, so i'm not sure birth of the lamb works on it. i'll try to find out
could you tell me what error it gives you, or does it just crash. also are you using a legit version of afterbirth (non-pirated)
Im using a steam version, and it just crashes.
And how do you think I downloaded the mod if I have a pirated copy of Afterbirth which hasnt released?
if you can handle it, just use the GFX folder, then edit the character using the character editor
This mod is for rebirth, but have started work on an afterbirth version
Bosses who weren't previously in boss rush.
My god, are people actually downloading this!?
There should be a 'Report Mod' button.
Can't you idiot ask the creators to upload their mods here, if you upload those mods just for the sake of the mods being on this website?
he didnt steal he just made it that much easier to find and download i went on the reddit page and i didnt see a download anything on there
"This is not my mod"

Oh, screw you.
