Giana’s Return aims to be a worthy UNOFFICIAL sequel of “The Great Giana Sisters”. “The Great Giana Sisters” is an alltime classic made in the late eighties mainly by Armin Gessert, Manfred Trenz and Chris Hülsbeck. The game gained impressive attention but has been damned as Super Mario copy. More information can be found here: http://en.wikipedia.org/wiki/Great_Giana_Sisters
