I just completed the game 2 days ago and have been pondering the ending. I'll give you some context as to what I am pondering:
I was playing the game while my girlfriend was over. Her father died from alcohol poisoning when she was in the 5th grade, needless to say, her father abused alcohol frequently. She wanted to see what the game was about and how accurate of an allegory it was. She had teared up by the ending, in particular at the cable car scene where "Monster" sits on the cardboard boxes looking disgusted with himself. She said that it was brutally accurate and brought back some harsh memories. But the ending pissed her off in a big way. She interpreted pushing Monster into the cyclone as "leaving your father to die and ignoring him." I just wanted some thoughts on the ending, to see if people agree or disagree, or if they can present another point about the ending.
