The characters being a wide range of sizes is a bit of a disappointment, it makes it a bit more difficult to use with Godot, but i will see what i can do, i can use the tiles which is nice. sorry for the complaint and appreciate the reply.
i dont see how different sized enemies makes it more difficult, just use sprite 2d with an animation player and keyframe the collision shapes in the animation player,
failing that you can always scale the sprites in the game engine
