The first update is here.
Now you can properly save the game. 
When you boot the game and a save is available you can continue raising your current bird or start a new game.

Even though coins were already being collected under the hood, now you can actually see how much coins you've got.
You still can't do much with them though, but it's being worked on!

Last but not least, some changes have been made overall to texts and UI elements. Together with standard bug fixes.

Please enjoy the game even more!
