Love the game but delayed, and crashes

I love this game, after the last update it doesnt work at all. Keeps crashing. While in the challenges it crashes and or just pauses randomly then by the time it starts again it kills you because your in the air and hits a duck. Also its as if its going in slow mo. Fix it or Ill have to delete it because havent been able to play in two months.
