Space Invaders Game
This next task is CHALLENGING. You may not get all of the parts completed. You must complete the tasks in order, so Part 1 first, then part 2 etc...
You are going to build the Space Invaders game. This will run on the Microbit. You will need to "Watch the video for 30 seconds, pause it and then do what you saw in the previous 30 seconds". 
YOU MUST NOT JUST WATCH THE VIDEO AND LET IT PLAY THROUGH AS YOU WILL NOT REMEMBER THE STAGES!
