17600, S for omnipotent. Not bad.
A great and unique way to kill some time... and some weak people from this miserable, pathetic planet >:-)
I believe that this game has some room for improvements, like making the planet bigger and with more things to destroy, adding new cosmic weapons (like a supernova explosion, a gamma ray burst or a solar flare), and making the game consider the objects launched into Space as "destroyed" as well. Still a very cool game. I think we need more cosmic horror games like this.
Oh, by the way, the soundtrack is kickass!
