Really cool use of the theme! The best score I got was 45. At first I was just trying to swing and hit the ships but then I learned how to let go of the rocks to slingshot them into the planes and did a lot better. I also liked how the world was infinite (or seemed infinite) so I could escape a sticky situation if I needed too. The one thing I think would've been really cool if there were little tiny stars in the background to give it more of a space feel. Thanks for sharing!
