Unable to play on iPhone 6s Plus – Mega Run - Redford's Adventure Review

I recently purchased an iPhone 6s Plus, and now, this game will no longer work. I can open the app, but am unable to choose a level to play. I was able to play on my 5s without an issue. I re-downloaded the game losing all of my game data thinking this would solve the issue, however it did not.
