Keeps crashing!

I love this game and I was enjoying it very much plus I was half way through the game when it crashed. I kept trying to open the safe behind the painting but crashed every time I touched the second side of the frame; I restart the game several times with same results, touch the second side of the painting frame and crashed for the tenth time. I uninstalled the game and installed it again several times but with the same crashing results. Each time crushing on a different puzzle; as soon as I touch to start solving the puzzles it crushes and each time takes me to my desktop. I have an iPhone6 with the latest iOS updates. Too bad it crashes on me this much, I was enjoying this game quite a lot .
