Let's setup the logic for the food and the ghost to be in different quadrants. Finally, the game over component is now upon the game. If the hero is `touching` the ghost, let's display `game over`

```blocks
let hero = game.createSprite(2, 2);
let food = game.createSprite(4, 4);
let ghost = game.createSprite(0, 0);

The game over component is now upon the game. If the hero is `touching` the ghost, let's display `game over`

**Do not disconnect the conditional statements blocks from the remaining blocks. We are focusing on this section of the code and are not showing the entire code**
The game can also use the buttons. Let's create a `while` loop for button A is pressed. If button A is pressed, the micro:bit will display the word Hero. Let's use a `while` loop for button B is pressed. If button B is pressed, the micro:bit will display image of the hero.
