Is there a possible way to change what models you can play as? I've so far used all four of the characters you can play as and gotten relatively far with each of them. I understand that the game will likely not be updated anymore with this latest release, but I also understand that it was made with Godot and as such might be easy to add custom models? My knowledge of programming is barely more than surface-level, so forgive me if that's not at all how that works.
