I understand this bro, but if the game is caught in copyright law it can at least be deleted, I don't think it will go that far, as I said the dev of this game, did not make this one or others with third-party assets to put up for sale, he makes games for fun, showing a little game dev behind it and posts it for everyone to test it, So I don't think it can go too bad.
your fansmade of berserk is beautiful unfortunately I'm not the one who created these laws... this is a bigger problem... if you made guts in the female version with boobs you wouldn't have had any problems... as it has been modified as happens with art with ai... today It's very hard to do fansmade, I've seen many devs reunite as soon as bad guys from justice arrive. you have talent you can create something big.
