Ecco: The Tides of Time (1994)

Mega Drive/Genesis: a dolphin's song becomes communication, investigation and a way to interact with danger. Swimming through currents and reading underwater space gives exploration a physical grammar beyond doors and platforms. The enduring idea is to make the animal's abilities organise the adventure. Expect cryptic routes and demanding hazards beneath the calm-looking water. This refers to the sixteen-bit cartridge game, rather than the eight-bit adaptation or the distinct CD presentation.
