Well, so far i'am in chapter 3, note that the vacations ended for me, so i may take time to publish the fourth chapter since i have a lot of things to do.
I tried to imagine Antasma has the kind of guy that is the only sane man and comically serious, he try to act serious, haughty and arrogant but that only make the scenes even more funny.
I also prefer the humor because the Mario universe isn't made for dead serious things, instead i waver between the humorous scenes and more serious one.
