After you finish the 3rd character's route, you are automatically taken to the final route. It was supposed to appear on the main menu screen as a separate final/true route. But was having issues getting that to work. So due to time constraints, I just had it give you a message that says that you completed all the other routes and that you are going to play the final route before automatically jumping to said final route.
Again, thanks for the feedback! And I will be sure to give your game another try to see if it works with my headset. ^_^
