EXTEND: Let's experiment with making small changes to the game!
- Find and change the starting value of time from 60 to any other value. This changes how long you can play!
- Find ····if·time·%·2·==·0:¬. Change 2 to 3. This will make stars appear less often!
- Find sprite.event_key_release("space",·release_key)¬ Change "space" to "up".
Run your code and press the up arrow. You've changed the key that causes the hedgehog to launch!
