Now it fixed in new release :D
It should work, there is every thing fine with Rakugo it self, probably there is some error in the question it self. I will check it.
Way godot works it makes that first time it load Rakugo plugin it load it in bad way.
So try reopen project. I will look it to that, but it should works.
Do you have any error messages ?
Just tell what is your game about on game page.
For example game genre and short version of intro to game story.
I think if that if you write what this game is about more people will interested in donate/check out the project.
