Can't say I was too thrilled about Ollie's ending overall
But uh, at least the route defaults to Marlo if you don't start from the beginning, and at least that's a much better ending overall
And also, there's no more further updates to this. This is how it ends. All we can do is hope the author continues on with spinoffs but I think he's currently working on something completely different, and much smaller titled "Sailor and Otter". Understandable considering this has been an insanely long project which went on for years now, and the author probably wishes to do something else and try experimenting before diving into another huge project
I don't think it'll be released to public soon but we'll see what that would be about.
