I broke the game. Twice. I'd like to think both endings have their own lovely meaning to them.
Coming home at night, finding the wife and daughter resting peacefully, not able to do anything. Stuck at the apex between life and death. No progression. No continuing. Home, safe, with his family, with nothing to hurt them.
Then, taking the daughter to the park after the wife kills herself. A white screen, nothingness. A sense of purgatory. A place free from the horrors of the world around them crumbling, the pain of a lost wife. There is nothing, but a father and daughter, playing piggy back for eternity. One last glimmer of hope.
Or it broke. Either way.
