Fish Fillets NG is strictly a puzzle game. The goal in every of 
the seventy levels is always the same: find a safe way out. The 
fish utter witty remarks about their surroundings, the various 
inhabitants of their underwater realm quarrel among themselves 
or comment on the efforts of your fish. The whole game is 
accompanied by quiet, comforting music.
