Fun game, but... – Gravity App Review

I used to play this game all the time on my old iPhone, and it was pretty fun. I liked to make apocalyptic situations where I made two planets crash into each other, and the result was mass destruction. But, when I upgraded to an iPhone 6S, I was no longer able to play this game. So, a little something I want to ask the developer: Can you please upgrade the game?
