I just remembered something from the game's developement: "...by blowing into the microphone, players can...summon a large gust of wind." This never showed up!!
You can blow and make the bits in the sky move faster, but thats it.
Yeah, also, in the announcement trailer, there was a different power up. I don't know what it was called, but basically, you could shout into it using the mic on the PSVITA, and blast things back.
