This game was amazing. I've played a number of these games that have an emotional message like Greyfox or Gone Home, but this one blows them all away. The only negative I can even think of might be tone, which is all over the place. At first it seems like horror, then fantasy adventure, but then to highly touching and emotional.
It was also good to get a reminder of a very real disaster in another country that affected a lot of people. I am assuming several things in the game are related to the Fukishima nuclear plant disaster following the tsunami.
Any parent that likes games should play this one. Then go hug your kids.
