Played just fine on my iPhone 6. The atmosphere and music are incredible. I was really surprised with the the monsters, giants, and surreal creatures as well. There are no glitches on the tower, tree, or other areas. If you cant get past it or get something to work its just because you havent figured it out yet. Tap above the brothers control circle (not on) when you want that brother to let go and swing with the rope on the tower. Hint: When youre sitting on your brothers shoulders to free the woman theres something you need to do first so they worship you instead of kill you. Be patient and youll figure these areas out. They are not glitches.
