I actually had a good time for a few minutes, coming from a busy work day, it was the perfect game ^^ But it would be nice, to see more variety in use of the mechanic, maybe in future updates? I'd like to see that :)

Well, it seems that this one didn't get finished, which is understandable.  It happens to every game jammer now and again.  But it would be nice to know what the game was going to be given enough time.  I see that the wrecking ball is the one "smash",  and that colliding with ships adds to a negative score somehow.  I'm wondering what the win condition was going to be?  Anway, better luck next time.  Perhaps its worth trying to complete the thought with this one, if only for practice.  I sometimes continue to work on a jam game to see if I can make something out of it.
