Lenin, [hide=]There are eight very, very secret "stars" hidden within the game. You can collect 7 of the 8 in any order, but you cannot get the eighth and final star until you've collected the other 7. Then you can go back to the last level and do some funkay time thing where you actually do go up and into where the Princess is, allowing you to nab the 8th star. More detail can be found here.[/hide]
