This app would usually crash my phone, requiring a reset. When it did open, any picture loaded into it from the phone's camera roll was really blurry, and the pictures that come with the game (of which there are only four) are all intricate patterns - not at all the best images for use with this kind of game. The menu also always froze during game play, so that to start a new game or access the menu at all I had to go back to the home screen and then reopen the app. Long story short, I finally got fed up and deleted it. I just bought Slider instead ($1.99), it's the first app I've paid for and it seems really smooth and has a huge preset photo selection. Spring for that instead of this crappy thing.
