The Spaceship will move toward the mouse pointer, hit the space bar for a rocket boost. This is a game I am teaching at the moment. I'm using this version to add each lesson as we are going through it. The final version is here: https://scratch.mit.edu/projects/99118710/ .
Based loosely on Al Sweigart's Meteor Dodge and Daleks Game for the Spaceship motion and recharge timer ideas. Check them out at http://inventwithscratch.com/
