Cosmo Keys

Save the Cradle.

A meteor broke the shield around the Cradle and flung its four Sky Keys across the stars. Poison poured in through the gap. It took the little ones — and SAMO, their guardian, with them.

Nobody stole the keys. A rock scattered them. Nasso is going out to bring them back.

What it is

A 25-level side-scrolling platformer across six worlds, ending in two boss fights. Run, jump, stomp, ride, and work out the route — levels 16 onward are hand-built puzzles rather than corridors, so getting through is as much about reading a room as clearing it.

The crew

You start as Nasso. Coins you collect buy four more, and each one carries a single ability that changes how a level is solved:

LYRA	freezes every enemy for 3 seconds — enemies stop, hazards and the clock don't
RUE	a burst that kills what's close, including the spike slimes nothing else can touch
VELA	six seconds walking straight through anything, drones included
CASTOR	never presses anything — he repairs you on the hit that would have killed you

Controls

Keyboard, gamepad, or touch — all three are first-class. Landscape on a phone.
