I'm making an app in Godot for creating a custom 2D characters to use for games. As for now it in the very early stages of it creation and like I said in the message one of the thing I am planning to add is Visual Novels and RPG character feature. I will upload a new Alpha version of it soon but it won't have the Visual Novel and RPG capabilities.
Since you need Art work for and this will also help me out as well.
Once I start the process of Working On the Visual Novel and RPG features I let you know once I start doing the fighting game features.
Happy Game Dev
