Haha, the intent was for a casual play to have a more conclusive ending so that works out!
Those are all valid questions and left semi-open ended for an upcoming project.
(Would be too tough to respond for most without heavy spoilers on here but routes 1-3 are variants using info from the 4th, which is “canon” technically, and discrepancies are there for a reason!)
Thanks again for playing and hope you will support our future releases too. :)
