This girl has folded a paper aeroplane, with a wish written on it: she'd love to see her mother back. Let the aeroplane fly as far as possible, and collect stars that are worth money. You can use this money to buy upgrades. The red, folded cranes are worth extra points, too: they temporarily multiply all the points you collect. In the beginning you can't navigate your plane yet, but after having gathered some more money, you can buy the 'Rudder control' option, which makes the plane navigable. Slowly you reach your destination: in total you have to cover 1000 metres. Good luck!
