Balloon Express Flash Game at Y8 Flash. Your goal is to fly your Balloon without crashing and deliver as many Mail Boxes as you can. A fail delivery makes you loose points and a successful delivery gains you points. When you deliver 25 Mail Boxes you will get an extra life. Avoid the Birds, UFO and Zeppelin that may damage the Balloon. Beware of the Storm Clouds (thunderclouds) as the lightning may hurt the Balloon too.
