Hi Metarevelations!
When we made and test Luna Engine, we always keep artists and non-coders in mind. From VXA, we had some pretty amazing games come out of it and feedback. I would highly recommend checking the public documentation over here: https://itch.io/t/490933/luna-engine-mv-documentation-and-tutorials
That way, you know what to expect when diving into it. Luna does not need that much programming knowledge, but it does require you to know how RPG Maker works.
Cheers!
