If you like romance, doom, and the great big sea, this game could be for you.
My girlfriend and I had a lot of fun playing through this game, though I'm not sure it holds a lot of replay value - maybe in a few months, we'll switch roles and try again, but the elegant simplicity of this story means there's only so much room for one playthrough to differ from the next. Still, even for just one round, it was a fascinating experience.
One thing that tripped us up is neither of us read too far ahead, worried about spoiling our own experience. My recommendation is that, at the very least, read each scene through beginning to end before you play that scene.
When we played, I curated a board of soundscapes to play in different scenes for immersion. This isn't necessary, but if you're interested, here are my recommendations:
MyNoise - Sailboat for the opening scene / anything on the boat (if your game has a more modern ship, try MyNoise - Tanker at Sea)
MyNoise - Irish Coast for anything on the surface of the water
Talisk - Echo a sprightly tune in the north atlantic tradition, for playing over the other relevant soundscapes during the Dance
MyNoise - In Utero for anything underwater
MyNoise - Chapel Voices to be layered under In Utero for a haunting vocal effect during the Drowning
