Reflection/Homework

1. How are While loops different from For loops?

2. Explain why picking up the fireSource allowed the player to keep making fireballs, without any other buttons being pressed.

3. Challenge: If "IF statements" didn’t exist, could you use While loops to implement the same behavior in blocks? If so, how?
