Hey guys!
Had to do a quick update once more! We had to fix a bug where it made it quite difficult to open Ninja girl's route. You needed to get 2 correct answers in the first day, and that was the only way to unlock her route, which wasn't our intention.
Now you should be given 4 chances within the 2-days to get at least 2 correct answers to unlock her!
Way easier isn't it?
Thanks to @krisiunas23 for telling us about he couldn't get Mie's route!
