FlatPack Interactive has just released a new version of BallFallDown Deluxe for iPad. BallFallDown is an open-ended construction toy that brings the classic marble run toy to the iOS. Players can design their own marble runs using a variety of balls, platforms, spinners, flippers, and tubes. Simple touch screen controls allow you to rotate, lengthen and shorten, and drag pieces around the play space. In addition, BallFallDown offers iPad-specific features that could never exist with traditional toys, such as teleporters that beam balls across the play area. Here is more info on the iPad game:
