A platform game based on the Disney cartoon of the same name, ported by the Brazilians from Game Gear (the Genesis version is similar). We play as Ariel or Triton, swim through the labyrinths, fight Ursula's henchmen, free enchanted characters.
Well, who doesn't know the Disney cartoon about The Little Mermaid? Aliel, a young mermaid and daughter of King Triton, falls in love with a man, and even a prince. In order to be with him, she contacted the evil sorceress, Ursula, who has long been hatching plans to capture the underwater kingdom.
This is a wonderful game that has been re-released on many consoles, only it's somehow inconvenient that men cut themselves into girly games.
Port from Game Gear. You can play as both Ariel and her father, Triton. The game was made in 1992 or later.
