This upgrade solved the compatibility problem with iOS 5. The game is now playable on an iPad 1. 

The difficulty is re-balanced by tuning the frequency of “blue” letters (Z, X, Q). 

As visual feedback for game ending condition, an animated bar would appear when the letters are piled close to the top. 

The repeat popup achievement notification is now fixed. This update also fixed a seldom crash related to quick loading. 

After all, the app name is revised to be search engine friendly.
