Miyamoto explains what the Super Mario Galaxy 2 black-and-white effect is all about

After Super Mario Galaxy 2 was revealed at E3, fans were left wondering about a particular moment in the trailer. In the video, Mario hits a switch and then the screen turns black and white. So what was that all about? Nintendo Power asked Shigeru Miyamoto about this in the magazine’s most recent issue.

“We haven’t revealed that yet but maybe I can talk about it…It’s an effect where time slows down. There’s a slowdown in time within the game – probably pretty much what you had expected.”

So it seems as though the developers will be mixing up gameplay mechanics in a few ways. We now know about slowing time down, the level where duplicate Mario figures copy you, and of course, Yoshi.
