GameSpot noted that "The game has a fantastic sense of style to its design that is reflected in everything from the animation to the unique use of the peaking fad, cel-shaded polygons." Many reviews also appreciated the ease of learning the controls and gameplay; IGN stated that "Sly is incredibly responsive, and though his size seems a little large at times due to his long arms and legs and the cane he carries, skillfully jumping and hitting enemies with precision is a quick study."
