This is very interesting - I’ve tried to make custom syntaxes for describing dialog etc multiple times, for embedding into game projects, especially since things like Ink aren’t really amenable to porting to other languages easily. So the multitarget/multi-language focus is very attractive.

One thing I will say though - I think something that would set a language/toolset like this apart, would be a high quality UI for showing how different parts flow into each other (a diagrammatic view as an essential / main view instead of just eg an addon).

I mostly say that out of jealousy after seeing the kinds of tooling that companies like eg Obsidian have for writing dialog and narratives
