In order for the pixel character to safely reach the green crystal at each level of the Boxed Boxes game, you must be smart and use logical thinking. The hero is in a square outlined by a dotted line, and in this small space next to the hero there is a cube made of an unknown material. This cube, together with the dotted frame, will constantly accompany the hero and help him overcome high obstacles that the hero cannot jump on. It's up to you to successfully use the cube and its minimal space to achieve the final result in Boxed Boxes.
