Our Extra-Terrestrial friends want to return to their home planet but their flying vehicle is run out of energy. You can help them by throwing an energy ball toward their vehicle, it will be power up whenever the energy ball hits the vehicle, and you will gain some score too.
The score you gain depends on the way ufo hovering and the way you throw the ball, basically curve ball will gain more score than straight ball. You have about three minutes to do your job, good luck and have a fun!
