Loved the story.
Technical babble now, I love the use of Godot as well and is much cleaner and better than the traditional renpy solution. My one complaint is the controls differ from those found in those vns specifically the enter button typically is handled as a click and the scroll wheel typically handles going backwards and then back fowards again only to the latest point you got to. If you have a git for the framework, I'd be more than happy to contribute those features to add a tiny bit more familiarity if nothing else.
