Thank you so much for linking me the Game Crediting Guide! It seems extremely useful and I'll give it a good read. That aside, I agree that I should stop accepting random unpaid contributions to my game, with the exception of very few good friends I can trust. The writer used to be an acquaintance of mine, but they utilized such relationship to actively take advantage of me, which saddens me very much. But I can't change the mistakes I've made in the past, so I'll be more careful in the future. Thanks again for taking the time to respond to me!
