This challenge is a really tough one, so pay attention: Modify the game so that the game window is four times larger than it is presently. To make this happen, the grid size will be changed from 32 × 32 to 16 × 16 for each square. This will double both the width and height of the grid. The snake body segments will have to be modified so they are also one-fourth their current size. This will make the playing field huge!
