My friend and I were working on a game called Learnloot.
My friend made art, writing, and other designs for the game, although at the time she didn't tell me where the designs originated from so I assumed they were for Learnloot specifically.
However, now, she wants them to be removed from Learnloot because they were her designs and not for Learnloot itself. However, I was never told this, and considering that they were given to me when we were designing Learnloot, I assumed they were for Learnloot, but she thinks I should've known to ask her instead of assuming.
She says that the similar case raised with a game that we both have played in the past known as Pokéfarm Q where the founder's wife created art for the game is not valid as PFQ is a company, not a non-profit (Learnloot is an educational soon-to-be-non-profit - but it's not legally incorporated yet, as it isn't ready to be released). Is this valid?
Note: This is occurring in the United States. We were working as a group and neither of us were being paid anything for it - it was just a project.
