The only thing working is the store – Color Zen Review

Even after restoring purchases, I cannot access anything but the store, the instruction slide panels, and the music mute. Absolutely no way to actually play the game anymore. My past purchases sit worthless. The prices in the store, by the way, are absolutely absurd. I bet you can still buy that stuff, too. Another negative is that it dwarfs any other app in size. My advice is not to waste your time with Color Zen.
