Very fun game
When I first heard "world defense" I thought it was going to be a satire of George W. Bush defending the Earth or something. It would also be a strategy game with sending squadrons. To be honest, I would have probably not enjoyed it as much if it had been like that. The best part was the easy gameplay. It was cool to see the damage add up, especially with how you got to see the Earth's molten lava the more it got destroyed. The music made it sound really alien, even though there were no aliens involved.
