And as an original buyer, I thank you tremendously! Performance is great on the latest stuff -- the iPhone 6 will be fine. iPad Mini 2 has 1gb of ram? As long as it has 1 GB of ram it should be fine. I play it on my "low end" device for testing, an iPad Air 1 (I think that's what this is), and frame rate can suffer if I have shadows on or 100% resolution. So generally I play it with blob shadows (or "torch/sun only", which is just one light for shadows) and at 50% resolution. Comparing the resolution, you can tell theres a difference, but I find that I quickly forget it as I play. I did get a new iPad Pro (the smaller one), and it screams of course on that device, but no different than the iPhone 6s. There's still some issues with random crashing -- I haven't been able to figure out what is causing it, but my best guess is just the RAM usage.
