Everything is Dolphins

From the Introduction: Welcome to Everything is Dolphins, a place where everything is - you guessed it! - dolphins. At its core, the world of the game is a sprawling underwater dungeon. Human civilization has been lost and just about forgotten in the annals of time, with now-ancient ruins dotting the barren landscape above ground; the Earth's waters have become pristine due to the lack of human activity. Under the docile surface, however, lies a maze of caverns, mysterious artifacts, and glory. The mysteries of the oceans are waiting to be discovered by you and your friends!
