Descending elevator is a large walkable platform. Unlike a regular elevator, it only has a single button, that when pressed, makes the elevator descend diagonally to the right. It moves within the rail background. It will stop once it reaches the terrain below. If no terrain is blocking the elevator's rail path, it will result to level completion. Descending Elevators are common in Alien cave levels, especially used to complete a level by pressing the button.
