The great giana sisters return (homebrewn dreamcast game)

does anyone know the history about the game ?
because i know the story behind this great game but i can´t tell the story in english.

but one thing is true Giana Sisters is an old SMB1 clone on the C64 computer and Chris Hülsbeck made the music.

 

i´ve found a review of the game and there is also some of the story why nintendo went ballistic about the game

The title sounds a lot like a hentai game.
