I mostly like this game, but there are two problems. One is that I think in order to get pleasing effects with custom photos I would have to crop them to fit the game before using them. It would be nice if this were part of the game.The BIGGEST problem is that the i is not consistently responsive to touch. For those that find the built-in picture puzzles too difficult, here is a hint. Work the puzzle with numbers, but before completely solving it, tap i and go change to one of the pictures. When you tap Done, it takes you back to your puzzle with the mostly solved picture.I like being able to interact with the author at his forum.

So first you really need to have the timer start when you move the first tile. So this way you can look at the tiles and see where they are before the timer starts. Second you should have the timer stay up while you are solving the puzzle. There is no reason to make the timer go away so you can't see your time. 4 out of 5 stars but it could definitely be a 5 star game.

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.

There's one infuriating problem with this app. If you pause for a second, a bar pops up across the bottom of the screen with the game controls, including the "New" button. If you're playing in Rectangle mode, which takes up the whole screen, you're likely to bump this button - and the game resets. No confirmation, just BOOM your game is gone. Makes me want to throw my iPod against the wall.Other than that it's a great game.
