 We want to identify the food so the player moves towards the food. We need to set the `brightness` of the `variable` food to 8. The brightness of the LED screen is expressed as a number between 0 and 255.

-We want to include a block from the Loops drawer called `While`. Then set the `While` loop to `true`. This code will be important for repeating code of the game logic of the game. The game will continue to run using `While` loop while the Boolean condition is true. Finally, include a `pause` of 400 milliseconds before the logic of the game begins.

 Let's create a function that will take care of keep the ghost pursuing the hero. We will need to a conditional statement that checks the position of the ghost and hero. The first condition will check if the horizontal coordinates of the ghost is less than the horizontal coordinates of the hero. We create a function from the Game drawer that will check the coordinates of the hero and the ghost. Finally, change the x-direction of the ghost by 1.
 
 Then create another function that will take care of keep the ghost pursuing the hero. We will need to a conditional statement that checks the position of the ghost and hero. The second condition will check if the horizontal coordinates of the ghost is greater than the x-direction of hero.

 Let's create the third function and forth function that continues the same logic in the y-direction of pacman and ghost. We create a function from the Game drawer that will check the y-direction of pacman and ghost. Finally, change the y-direction of the ghost to continue following pacman.

 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.
