Gave it a try. I didn't care to spend time actually figuring out the controls and tried to jump to the other side of my boat which would have worked but there's an invisible wall stopping you. So I tried to just over the side of the boat and drown but that didn't work either. There was nothing else at sea with you so I had no frame of reference to determine if I was moving my boat at all. It was plainly a walking simulator prologue but I didn't play it long enough to trigger the cool apocalypse stuff like planes falling from the sky around you.

meh. not a great showcase demo. maybe the game is better beyond the prologue or maybe it isn't. who knows.
