After playing this constantly for almost 2 hours, I knew a lot about this game. The game delivers a very depressing and eerie atmosphere, where the only things you find are dead bodies ( Excluding Chloe ) and haunting reminders of the corpses. The further you are in the game, the more you learn that the protagonist is only fighting the truth; all his comrades are dead. ( Again, excluding Chloe; who will die anyways if you don't try to save her. ) Praying gives him false hope to try to find someone alive and well, his only friend being the temple, and the chance of someone or something being in there, or escaping with a friend. The messages gives itself over time ( Emphasis on MessageS. )
Sometimes, the only thing you can do is pray. Pray and live on false hope.
