Tiny Wings is back with a big update. Now there's local multiplayer in the HD version for the iPad, and a new racing mode called Flight School, which pits you against rival hungry birds. There are 15 hand-crafted stages, all Retina-optimized. There's cloud sync, so you can keep your progress saved across iPhone and iPad. Best of all, the update is free for previous owners of the iPhone version, and Tiny Wings HD is a steal for just $2.99.
