I love and highly recommend this game, its the best. Ive been playing for years on many phones, and "finished" the game quite a while ago. I have earned every character, world, and upgrade possible, I still like to play but there's nothing left to play for. The global chalenges are ok but I have no more use for coins and gems. You should consider a major update or Temple Run 3. Btw, never had to pay to play.
