In this thrilling jumping game adventure, help Jack save his family from the underworld's demons. Gather great many coins, clear out innumerable foes and use a collection of wild aerobatic contraptions to arrive at the exit toward the finish of each level.

Incredible Jack, a retro platformer, pays homage to the best of the genre; Take on seven mighty bosses, use springs to propel Jack into the air or across water, and bounce on the heads of your foes for points.
