KEEP YOUR HEAD ABOVE WATER
You're stranded out at sea and your rations are running low. This is a race. A race between you, the ocean, your former friends, and the sharks. Only the ruthless will survive.

IF ONLY THERE WERE A BIGGER BOAT
Devise a merciless strategy to reach safety while simultaneously preserving your rations, avoiding the sharks, and sabotaging your fellow castaways. Be the first to reach the raft and you won't die. Simple.
