Dont expect any help from authors.

Ive played this game for years. I decided to check into where I stood in the leaderboard. I then discovered that none of my game scores were being added to my all time scoreboard. I have asked for help at least 10 times. I submitted requests from the app itself, through the link to the n the App Store, and at the developers website directly. Several times each way. I have never received any response, not even once. Spend your time and energy playing a game from a developer who cares about the people who play their games.
