Really cool game! I like it.

However it would have been cool to see a bar that tells me when I can fire again and when I can use my shields.

Also it got rather repetitive after a while since it didn't feel like I was progressing too much.

But aside from that I loved how the earth looked and how amazing the panning and shooting looked. Good job!

Kill that pesky earth! damn hippies!

Pretty fun entry! I'm not sure what you're supposed to do after smashing all the cities...hit the space stations? It seems possible, but difficult to get rid of them all.

YAYYY! At last I get to play the OTHER side of Missile Defense! Points for fantasy fufillment!

I quite like way the 3D perspective works; I admit I've always wanted to be the guy dropping a rock on the hapless earth and then quickly panning the camera to see it land.

Quibbles:
Sheild's too hard to use! Or maybe the missiles are too hard to depth-guess. Again and again, I turned it on, only to find the missiles seemed to slow down and wait ofr it to vaporate before striking. The satellites are also way too hard to hit (I spent ages trying).
Also took me a few minutes to figure out how to play.

Cool game though!

What was I supposed to be doing?

Interesing mechanics.
I like it.
