Not working regular on IOS 12.5.7

I have an ipad mini 2 running iOS 12.5.7. However, I haven't been able to play this game without crashing for 1 or 2 years. It has also become very slow and crashes every now and then. From where?

If you want to say that I have an old iPad and I cannot play this game on my iPad, please say so directly. Don't play these stupid games...
