Endless Ocean is an entertaining video game where the players can navigate their way through the depths of the ocean using the Wii remote. Players guide their character using the pointer's cursor, visible as a bright blue dot. When players wish to interact with fish or plants, they can highlight them with the pointer and press the A Button. By doing so, players discover new species and build up their fish log. In addition, you can also befriend companions like a dolphin which will become your partner and with whom you can train and swim.
