I played the sixth level of Hammer. First, move the screw in the lower right corner to the top, clear the gray strips, move the screw in the center of the cross in the lower right corner, do the same in the lower left corner, and then remove the two long blue strips. Open the upper cross and move the screw at the middle point to unlock the cross, and finally use the slope to clear the level.
