-**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.
