Video Issues

I have an iPhone 6 Plus. I loved the idea of this game after watching the gameplay trailer on YouTube. There are major video issues. The background is black. The characters and buildings are invisible. All I can see is the ground. I watched the trailer again, where I should see Nubs house, theres nothing there except for the smoke coming out of the chimney, but the house and chimney are invisible. Please fix this. I really want to play the game.
