The Sailor's Dream is a story. A story obliquely told in snatches of memory that you uncover as you explore its ruins, shacks, and ships.
Your interactions don't change the narrative, they simply push it along, from chunk of text to twinkly sea shanty. There are secrets to uncover, but if you're paying attention they're simple enough to find.
Is there enough to do here for The Sailor's Dream to be called a game?
