From what I understand, this game has been placed so far back on the back burner, that it might as well be a cancelled project. The artist is pretty much focused on their doujinishi.
That is honestly disappointing and sad, I went to the artists pixiv and even some of their japanese supporters were asking when the artist was going to start the project again.
But we still have another great Fart RPG game on our way (Lost Treasures by Aerodynamics), So I'll have fun with this trial version, thanks for the info.
