What is wrong with my game???

I played the free version of Barn Yarn and got hooked. I paid the 9.99$ plus taxes for the Premium version and it was doing well. At one point, the screen almost froze and now, it is so slow, it gets me angry.

Is there a way to resolve that matter? When you pay that price for a game, you expect it to be fine.

Let me know...
