COCOON

COCOON is the directorial debut of Jeppe Carlsen, the lead gameplay designer behind LIMBO and INSIDE, and the elegance of its central idea is what most players remember about it. Each world in the game exists inside a small orb that you can pick up and carry on your back. You can also enter that orb to step into the world it contains — and when you're inside, the orb representing the world you came from is now just another object on your back, waiting to be carried or set down.

The puzzles spread outward from that recursion. You learn to nest worlds inside worlds, to combine them, to drop a world into one of its own neighbours, and to use each orb's unique unlocked ability as a tool inside worlds that don't natively possess it — firing projectiles, revealing hidden pathways, triggering switches across boundaries. The game introduces these layers slowly enough that each new mechanic feels like a small revelation, but never explains itself in writing; the entire experience is essentially wordless.

The biomes you traverse are designed as the relics of an ancient civilisation, each visually distinct — industrial structures, organic caverns, biomechanical alien machinery — and connected in ways the orb mechanic exists specifically to expose. Powerful guardians defend each world and become boss fights tuned to whatever new combinations of mechanics the surrounding chapter has just taught you. The pacing is tight, the runtime modest, and the experience entirely undiluted by anything that isn't part of the central idea.
