Let's setup the logic for the food. If hero is `touching` "food", increase the score of the game by 1 and `set` ``x`` -direction of food randomly randomly from 0 to 4 and `set` ``y``-direction of food randomly from 0 to 4.

Let's setup the logic for the food and the ghost to be in different quadrants.
