Extend your program!

  • You could try changing the sprite, background, or object that the sprite collects.
  • Creating a timer can make your game even more challenging (hint: refer to lines 42 - 48 in the example activity).
  • Try having the game speed-up over time (hint: Try using a variable to control the speed of the interval event).
  • Make your character say a phrase just before they "Blast Off" to catch stars.
