Cocoon is a puzzle adventure where you play a winged creature transporting orbs through a mysterious world. The twist is that placing orbs in a portal grants access to the worlds within worlds and creates a complex nested puzzle.

Play involves traversing the world-leaping mechanics to decipher a mystery at the heart of the cosmos. Finding and manipulating the orbs are key to progression. Each one has a unique ability that functions as a tool to solve puzzles. In this way, you uncover hidden pathways, fire projectiles and trigger switches. You also need to take on large guardian enemies in challenging battles.

As you progress you discover alien environments and biomechanical devices left behind by an ancient civilisation. This enables you to unlock more ways forward as you journey through industrial structures and massive organic caverns.
