Great game! Adding to mjrb4's suggestion of acceleration, the SmoothMover and Vector classes at http://www.greenfoot.org/programming/classes.html allow for easy implementation of acceleration. To see an implementation, check out my Greenfoot project at hhttp://greenfootgallery.org/scenarios/3072 The private method "travel" in the Planet class uses the most acceleration in the project.
