Nice little game and good story!
I kinda laughed at the intro explaining the different religions :D
Got all the endings and think that the game idea fits the theme very well...you can't save everyone! And if you don't pay attention you might even lose all of them.. great catch in that! I like the music and sounds, while sounds may need a little polish here and there (waves are quite noisy and too repetitive I think for instance).
The game itself is very short, there is not much to do, but the dialogues are good and the story feels nice.
Overall a good entry!
