The flow chart is super clever and well thought-out! Nice work.
I’ve seen something else that helps steer people though decision making about worldview, a book called What’s Your Worldview? written in the style of those old choose your own adventure books.
I think the important distinction between these two projects is that your flow chart leaves no room for another religion. Perhaps a Buddhist needs to discover that a monotheistic God actually exists? Or a Muslim needs to decide whether one of the other Abrahamic faiths actually has better explanatory power of the facts of the way reality is? What do you think?
