It's an unusual concept to design a game on, but a decidedly necessary one none-the-less. I feel bad that there is no happy ending for Sam. The bullying doen't stop for her regardless of what we choose. She either learns it's her best friend behind it or Olivia. The students who ganged up on her suffer no consequence for their actions and no remorse for their awful behaviours. Honestly, I'm not quite certain which ending is worse.
Thank you for writing this. It must have been difficult, but I'm glad for the necessary message it portrays. Good luck with your future game building.
