(Spoilers)
I love the way the sea looked and the boat bobbed, the waves felt genuinely scary. Though it was pretty immersion breaking to see a buoy off in the distance that I thought we were moving towards, but after waiting for some time realised we would never reach.
I have no idea what the notes on the ground were about, at all. Or the computer. There were parts that seemed to be about suicide, or about letting the people you love know that you love them, not bottling things up... I got a lot of that from the ending and computer note.
Which, on the ending, I have no idea how I guessed the code, but is there a way to figure it out without guessing??
Anyway, great atmosphere and visuals. I'm very curious about the story, if there's anything to figure out or if its supposed to be left ambiguous.
