You have a rather big oops in the game story. Meg trusts the MC, and tells him that her mother was killed, when working as a doctor. Yet, her mother shows up, and almost kills the MC?? NO. This is a plot hole the size of Rosebud. ( If you didn't get the reference, it is from Citizen Kane.)
When I was an 18 year old, I asked Orson Welles two questions about that movie. When he heard them, he put down his drink, and walked out.
The questions were these: Was there anyone else in the house when the Charles Foster Kane died, or any recording devices running? No, was his answer
The second question was this: Then how does anyone know what his last words were?
Long winded, I know, but the point is this; Your mom can't be dead if she tries to kill your boyfriend.
And yes, I thought about her fibbing to him about it. but I think at the time that she told him, she trusted him enough to tell the truth.
