Unfortunately, the Apple TV app requires a separate $2.99 purchase -- but if it is as good as the iOS game, that'll be money well spent. The Apple TV app features split-screen multiplayer; players can either use the Siri remote, a dedicated game controller or an iOS device to control the big-screen action. The Apple TV app uses iCloud to sync progress with your mobile devices, and it feature the same array of game modes and levels as the iOS version -- including the five new "flight school" levels.

If you bought the iOS app years ago, you'll get those new levels, and Illiger also finally upgraded the graphics to support the higher screen resolutions Apple introduced with the iPhone 6 and 6 Plus. There's nothing else new here, but if you haven't tried the game before now's a perfect time to give it a shot. The adorable graphics, procedurally generated levels and excellent music are all as charming now as they were when the game launched way back in 2011. If you want to give it a shot, the update is live in the App Store now.
