Some games are fun because they make you feel powerful. Sink or Swim is fun because it makes you feel helpless at first, then slowly hands you competence through repetition and stubborn experimentation. It's one of those classic puzzle-action experiences where the challenge isn't only the hazards on screen, but the process of understanding how the level wants to be solved. Every stage feels like a problem that you don't fully understand yet, and the satisfaction comes from finally understanding it just enough to survive.
