So, I've been having a few issues, mostly with the characters. Eika is completely fine and I think Seija is fine, but for me, Satori is appearing as a worse version of Isaac with none of her special abilities and having the mod on puts every single character's speed go to 0.10. For the items, they are fine from what I experienced, save for the Tengu Camera which crashes the game. I'm no expert on how to fix this, so I need some help because this is a great mod that just has some things to iron out.
