Echochrome requires the player to control a moving character—which resembles an articulated wooden artist's mannequin—to visit, in any order, particular locations on the surfaces of collections of three-dimensional shapes. The locations to be visited are marked by shadows ("echoes") of the moving character. When the last marked position has been visited, one further echo appears which must be reached in order to complete the level: scoring is simply a matter of timing completion of each level (or a course containing several levels).
However, the character cannot be directly controlled by the player: it moves autonomously, following a path along the surface of each shape in a manner which keeps the path's boundary on the character's left (that is, in order of preference, turning left, proceeding straight ahead, turning right, or turning back on itself).
