You are inside a warehouse full of boxes of different heights. You start on the box marked with a black border you must reach the exit E. Boxes are marked with a number that indicates the height of the box. To topple over a box, just move in the direction you want the box to fall. If there is room for it on the floor it will fall over and you will land on its side. A box can only fall over if its way isn't blocked by a wall or another box.
