Rotating Bones 3D started from one simple idea: what if instead of making the character jump, you rotated the world around him? You play as Mr. Bones, a rolling skull, stuck in an ancient world floating in the void, built from ruins, traps and structures that look like something out of a fever dream. There's no jump button; there's only rotation. You spin the environment, gravity shifts, and the skull goes wherever physics takes him. Simple enough in theory; less so when the spikes show up.
