Cool idea, but very buggy and unpolished for now. Maybe you could make it on a better engine to start with, like Unreal? And DAZ characters with morphs would suit it well.
Oh, the bugs are just due to some oversights in my coding, not godot.
But thanks for the feedback, I'll be remodeling the characters soon, though DAZ style is a bit too realistic to me, I plan to do something a bit more cartoony
