Unity Playground Space Game

Unity Project for school prototype of Playground assets.  Is a simple space shooter, where you pilot a space ship and rescue aliens.  You can destroy asteroids but it will give you zero point.  You turn with a and d and move forward with w.  You can shot with space bar.  (Note: There is a glitch that whenever you shoot an asteroid that it will reset your score to zero.  It doesn't actually reset the score but it appears that way.  Just rescues another alien and it will appear again.)
