This is ridiculous! These idiots have too much time on their hands. I'm so sorry you have to deal with this. Also "I got a migraine playing the game", how is that your fault? Such an idiot.
I didn't get any FNAF vibes playing this so I'm not sure how they made that connection? It seems like they're reaching out of petty jealousy or hatred. Why not go turn that into love for something you like and leave MoRing alone? Morons.
Anyway, good luck with your exams! I will manifest you passing them without too much stress.
