This is the second game I played in this jam, and I didn’t realize it’s by the same dev as the other (Wintercoffin). You seem to know what I like: darkness and death. Like the other game, it’s too boomery for my Mac, so I’m running the Windows version on Wine.
The game is visually interesting, but the whole purpose seems to be to move in a straight line. Also, the sailing vessel is locked to the view yaw and, amusingly, it can strafe.
Sailor’s Grave is visually nice, but it’s the same visual for a long stretch of time. For boating games in general, I would recommend putting lots of stuff in the water, adding fishing and crew interactions (onboard romances, drinking games, etc.), or adding a time warp feature. Without other elements, it’s just a big blue watery road. I prefer Wintercoffin because of its visual variety and the promise of more to do.
