Have you done the boss fight against her? She's going to be the next Orin for the amount of ragequits with her screen flipping gimmick.
I did it almost 30 minutes after posting the comment and oh boy did I flip tables. The only stage 5 bosses that I hate are Orin (fuck you zombie fairies) and Shou (double fuck you curvy lasers), but screwing your interface is almost as if she was trolling us...
