I just woke up in the middle of the night with the realization that I should make cars (and other objects) fly! No, not flying like an airplane, but flying as in hit by a giant metal ball. Objects thus airborne can crash into other objects, damaging them and setting off pretty neat chain reactions!

Oh, and I also added trees that you can destroy. However, they do not count towards the score and completing a level.

P.S. The video is a bit wonky; I need to check that screen-capture software...
