Ecco the Dolphin is one of those games that looks deceptively chill—you're a dolphin, swimming around in gorgeous blue waters, doing flips and chirping at fish. Then suddenly you're lost in a maze of caves, running out of air, and getting bodied by sharks. The Sega Master System version is surprisingly solid for its time, with this weird mix of serene exploration and "how was I supposed to know that?!" moments.

It’s the kind of game where you’ll memorize enemy patterns just to survive, but the atmosphere—those echoing whale songs, the way sunlight filters through the water—makes the struggle weirdly worth it. Not for the faint of heart, but if you like a challenge with style, this dolphin’s got your back.
