If you loved the classic platform games of yesteryear -- the ones in which a beloved hero would run and jump his way through simple side-scrolling levels on his way to rescue a kidnapped princess -- then you'll enjoy Jumpin' Jack. Only instead of simple side-scrolling levels, Jumpin' Jack features seven stunning game worlds packed with vibrant detail, and instead of rescuing a princess, Jumpin' Jack sets out to save his wife and children from the demons of the underworld.
