Spoilers!
I guess the bad ending is when Mr. Teacher jumpscares you after choosing the wrong answer too much? Also, do the choices before the little quiz matter?
Thanks for playing! Unfortunately after I translated this game to English, the context and satire is quite specific to a certain country's situation, so it might be hard to understand for others. I'm sorry!
SPOILERS
There is a good end and a bad one! The jumpscare for choosing the wrong answers are game overs.
Hints to get the good ending; do not stay silent, be true to yourself, even if you're not fine. Also the teacher's name is "Ono".
