Earth Annihilation

Earth Annihilation is an oldschool Space Invaders tribute shmup but is way faster than the original. Invaders can shoot in all directions and some of their bullets have inertia. To counter attack you can speed up or down your ship . To gain lifes you have to collect coins. All bullets on screen changes into coins if you destroy the ufo and when you clear the stage.

The game is looping indefinately and is very manic.
