Gimmick! is a platforming game by Sunsoft for the Famicom. It features cute graphics, slick star-throwing physics and a rockin' soundtrack thanks to unique Sunsoft sound hardware. It's pretty challenging despite its looks. It was also released for the NES in Scandinavia as Mr. Gimmick, but that version doesn't have the extra sound chip that the Famicom verson has.
You need the good ending.
There is one secret hidden in each of the main 6 levels. If you get to the end of the sixth level with all the secrets and having used no continues, you will get to an extra level. Beat it to get the good ending.
Getting to the end of the sixth level without all the secrets or having used a continue at least once will get you the bad ending.
As far as I can tell, this 10:29 run by becored is the 100% world record.
