After a short stint wandering the orange canyons of Cocoon's opening area, you come across a curved groove in the ground. At one edge sits a large metallic ball, which you grab and yank until it reluctantly leaves its rectangular base, yet remains connected by a chewing gum string. Once the gum's elasticity approaches its limit, the base starts to move too, gliding across the mouth as if you're opening a zip.
As a puzzle adventure, is in figuring out how to overcome obstacles and progress, but it's also in the execution. Taking hold of the ball in this instance is an obvious course of action given that the beetle-winged humanoid you guide around can only manipulate the world via a single action button. You drag the zipper along the groove and that activates a platform. Job done. But this is a far more pleasing exercise than pulling a lever. The tinfoil tint of the ball, the pliability of the gum, the pink flesh that ripples as the zipper makes its journey. It's all so very tactile.
