Just one question. Even though my accelerometer is working fine..when I bring two matching pieces nearby(by adjusting device position), those pieces do not join..this happens sometimes....What could be reason?
Improvement : I observed that when you launch game by selecting any image, all the matching pieces stand close to each other and puzzle becomes easy to solve. May be you have to add logic to scatter pieces so that there should be some difficulty to search for the matching piece. (This is my personal observation, it may not be happening everywhere)
