Running Away From Space

Running Away From Space is a project made for Ludum Dare 42, for which's them was: "Running out of Space".  I decided to think outside the box, and take "Running Out of Space" quite literally.   All the player has to do is to dodge the asteroids, and get back to their spinning spaceship.   

There is no end to the game, there are infinite levels, due to a very simple random generator script, which randomly places the asteroids around the level.  What score can you get to?
