Gravshifter
Gravshifters are puzzle elements that are move objects within a cylindrical field. The gravity within this field is oriented to point away from the surface with which the field first makes contact. Like drillers, gravshifters only function when pointed at specific surfaces, which have a distinctive pattern. The player can also walk sideways or upside-down on these "gravity surfaces" even without the use of a gravshifter.
