An update to On The Wind has just been released! This adds two new game play modes, Zen, and EX, and lots of extra achievements to go with them.

Zen – Relax, you’re invulnerable. Just enjoy the view as you fly through the seasons.
This is almost exactly the same as original mode, the only difference is that the last leaf is invulnerable and you can’t get a game over.

EX – Faster, Harder, Shorter. If you’ve mastered original mode see how you do in EX mode.
The world scrolls past faster, there are more leaves to try and collect but they’re spread out more so you’ll have to do a lot more work to collect them all, and the year is only half as long.

You can choose which mode to play by swiping up/down on the main menu.
