Love to play Cookie Run

I love to play cookie run but I dont like time I upgrade or evolve treasures ex. I upgrade treasure 20+ times with coins because I dont have many crystal that the success is fail you should fix this its to have success chance upgrade treasures with coins is high chane because some people want to play with their skill than purchase crystal and use it to success upgrade or evolve anyway you may use fuction sum success chance % everytime upgrade until 100% to success upgrade or evolve treasures
