Will you accept ideas for this mod?
nice addition to the afterbirth mod i'll use them together
Is there a reason I don't have seal of approval on this?
You haven't stolen any aquatic animals from Sea World. Also, maybe because the hitboxes on Monstro and The Haunt seem a little off, because of how they naturally look different to their replacements. My best guess, at any rate.
Ah, that makes sense. These were the best I could come up with to replace them.
Trust me, I could not do better. Also, maybe because having Napstablook as a boss contrasts with Napstablook as the lost in other mods. Either way, I like this mod.
Yeah, but Asriel is in the Extra Version, and is also a boss, otherwise I wouldn't have.
