working on three iOS projects at the moment, and the first one has been announced. Party Wave is about surfing, which Sakaguchi describes as one of his passions.
According to the trailer, you flick around the screen to guide surfers through dangers until they reach the "party wave," after which you play a minigame to keep them surfing and away from encroaching bad guys.
Party Wave looks like simple fun, which should make it perfect for the iOS platform. Sakaguchi didn't share a release date or price, but he says "it's nearly completed. Hope many people enjoy it when it's available."
