Saucer Shooter!

It's game over, earthlings!

Prevent the invasion of Earth by shooting down the alien flying saucers before they get here!

Game play tips:

This is not a reaction game, so put away your rapid-fire thumb. The invaders think they have disguised their attack patterns well, but there is a vulnerability---discover this and exploit it to amass a high score.

Permissions:

Saucer Shooter! is completely free, but it does have some advertising and therefore needs permission to access the internet.
