I use clipstudio paint for all the art, but you can use similar ones that are free, and for animations I do almost everything on Godot with the animationPlayer node.
Ty i just bought clipstudio paint ex ill give it a shot :) (If you want any help with encrypting the game i can show you a really good way my discord is fatalliar ) <- use VMprotect i dont fully know if that will work with godot but it does with most engines :)
