There will definitely be an ending. The next few updates will lead into the final arc. I am only able to work on this part time, though, so I cannot say when it will be done.
hope you plan a sequel. I propose "Guardians of Freedom Academy of Exercise" as working title (until one with a good abbreviation is found)

There will be at least one more game in the series but it will not be a direct sequel.
