You use the left and right buttons to move the spaceship. Shoot lightning by pressing space. Kill hippos and rocks by shooting them with lightning. The present increases your score. You have 3 lives and if you get hit by a rock, an orange or a hippo, you lose a life. When you lose all your lives, its game over.
Double click the green flag if you have lost your 3 lives or if you press the stop button.
