To play, simply guide a red balloon from its birdcage out of a house, through the trees, past the clouds and into the heavens without losing it below the bottom of the screen. Each of the five levels presents a unique and challenging maze that requires you to quickly tilt the iPhone to direct the balloon through tight openings. The first level (the house) moves slowly, allowing you to easily move around bookcases. Things get crazy once you hit the third level. Not only are the tree branches longer and more difficult to maneuver around, but the game also moves significantly faster.
