I collected all of the Star Coins in World 8 like it told me to do, however I did die eight times in the last level of World 8 (Bowser’s Castle) in which I activated the Super Guide. I have beaten the level myself and got all three of the Star Coins in Bowser’s Castle later on. Should I still be able to play the last level in World 9? What’s going on?

Do you have to use the Nunchuck with it? I saw the icon on the back of the box after I got it home and if I do have to use it, then I’ll just return as I really dont like the nunchuck, I’m not cordinated enough. Can I just use the regular controller? Many thanks.
