I will investigate the bug it seems the general variable for the game completion is broken but not in all path, I will give a try next week, I'm focus on Tower of the last Demon tight now.
I'm really sorry, I'm really lacking of time and I don't go to the Ruru game but I'm planning to add a browser version so when I will do it I think I can add at leleast a feature where the the bonus zone is directly accessible.
