STAY ALIVE!!! Though staying alive was never been this hard.
You are in a "C-570D" space ship. You got lost and all of your ammo already finished. All of a sudden you entered in an invasive monstrous alien zone. Save yourself and the ship from collision with any of them. Guide your ship by tapping at a void space with a straight path.
The more you can stay alive the more point you gain.
You have to practice a lot to become an expert. And after that, you can challenge your friends to check how expert youre ;) . Enjoy the game, best of luck!!!
