when you collect coins, if the shop isnt basiclly centered in your screen then it slowly moves your screen so the shop where you are collecting coins from is centered. when it moves your screen you can move the game around yourself it forces the screen to move. it also takes to long for the screen to move and then once the animation of the coins coming out is done there is a few seconds of wait before you can freely play the game again its super annoying and overall takes to long
