Astra. The person you are quoting said this:
Art and animation on the internet based off on a game that you didn't even make (talking about the base FE before your changes).
He never said that you didn't make the art or animations. He's saying you didn't make FE itself.
I'm just trying to help the guy who's trying to help the OP.
Though, I do agree the OP should have asked for permission because theft is bad. Hopefully it all gets resolved in a positive way.
Have a great day everyone. :D
