Spoilers, I guess...
What I really appreciate about this game is how it kept leading me to believe (or I kept assuming) I knew how it was going to end, only for my predictions to mean nothing.
Before I opened the game, I saw the old man and assumed it was going to become some cancer story, then the game started and I realised we were living through war. So I assumed a bomb would destroy the house in a big, sad explosion that confirms finality. Then, the frightened man grips your hand in terror and comfort and the house buckles under its own weight. Like real war, there was no way for me to know until it happened.
It really was quite the ride. I kept just wanting to play checkers and not think about the end. Nice work, man! (:
