NEW STUFF! Well, turns out most of the world, including me, lack middle mouse buttons. So you can also now use the z, x, and c keys to fire missles from your silos to wherever your mouse pointer is. I got a new super duper high score using this new technique! Also, the closer to the ground the missles are when you shoot them, the more points you get.
Play, and have fun!
If anyone ever plays this, and you wanna submit your highscore, email me and I'll post it here.
Mine: 187200 :-)
