"""Now, here's the Super Guide block. If you die many times in a level, this block will appear and you can activate the Super Guide for that level. When you activate it, you'll see 'video' of Luigi running through the level. Since this is World 1-1, the guide is running through the most basic of tasks, almost like an instruction manual of how to play a Mario game. At any point, you can take control of the demo, so now I'm playing Luigi. What the Super Guide doesn't show is the secret areas, it's meant as a way to show novices a way to complete the level. But in the demo you can explore all the hidden areas. If you left the demo to run all the way to the end, it would give you the option to start the level over to clear it on your own, or if you just wanted to use it to get through the hard parts to finish the level and continue, you can do that.

I will say that when the Super Block icon appears, I feel regretful and guilty that I let that happen. I've often found that when that happens, that it inspires me to do better and clear it on my own. People who play the game without letting a hint block appear will get a little special something on the title screen after they finish. There'll be stars that'll appear on the title based on special things that you did in the game, and that's one of them.

As you collect star coins in each level, you can use the star coins to unlock additional movies that are created using a similar system to the Super Guide. These are called Hint Movies, and these show highest level of gameplay that testers and developers have achieved in the game. Things like Infinite 1-ups and Super Skills and locations of Star Coins. We have a video of these Hint Movies cut together showing off some of the testers' moves. """

The important bit for those who doubt this can be used as a free pass, is bolded. Miyamoto clearly says that the game gives you an option to either go back and redo the whole level yourself, or simply "finish the level and continue."

But there is an acheivement system, which includes a star on the title screen for beating the game without making a Luigi block appear at all.

I have a feeling beating the game with all the title screen stars will be a very difficult task.
