Mistwalker, the studio started by Final Fantasy creator Hironobu Sakaguchi, has launched its first game for iOS, Party Wave. No, it's not a game where you wave hello to friends as they walk in the door for your birthday party, nor does it involve coordinating a stadium full of people to move their arms up and down at the correct times. Party Wave is about surfing, one of Sakaguchi's passions.

Party Wave goes for $1.99 on the App Store and works with iPad, iPhone and iPod Touch running iOS 4.1 or better. It's an "action surfing" game that has players control a group of surfers as they navigate an ocean of obstacles.

Mistwalker is working on two other, unannounced mobile titles. Sakaguchi's Wii game, The Last Story, hits North American shores on August 14.
