First, I am honored you not only remembered the story but sought it out to read again. That is incredibly motivating for a creator.
As to the ending - I have one last story I am in the process of writing based in the Vogvhathos world, set after events of that and X.E.H.A. Rogue. Once this last one is written, I plan to go back and polish/patch and add to any stories people have said they wish more story of. Unfortunately, it is only me creating all of these so it may take some time yet. I may also not be able to continue to support mobile ports, as they are constantly changing requirements. It is one of my hesitations to patching these older Itch.Io versions of the stories, as I know many do love the mobile option. (I do plan to at least go back and patch the Steam versions to work more smoothly with the Steam Deck - mobile is more complicated, however.)
In the meantime, I'd love to know if there was a specific character or more that you wished to know more about. I could add it on to my "to do" for when I can come back to released games and add more to them.
