Aw hello there Gattin! It makes me sooo happy to learn that you loved DSGR!!! And is it just me or are you typing like Jaja would speak? lol ;)
There has already been a few updates, in that there is now a mac version, I uploaded a new build to fix some spelling/grammar errors as well as an annoying bug that prevents the Credits from playing at the end.
If you mean, will there be other Dream Savior Gakuen games, then that is a secret. Heh. But I hope so someday.
