Game won’t even open

App will not open.

I got this making game because it looked interesting and challenging. I downloaded it to my iPhone 8 Plus and when I tried to play it wouldn’t allow it. I would open the app, it would switch to a picture of a fireplace, quickly change to a 8 Floor logo and then shut the game down. I tried this several times and could never get it to work. I’m quite upset because I love playing mahjong and your game sounded and looked like one I would enjoy playing. I am therefore forced to give you only one star and say how disappointed I am in your product.

App says it needs a key when you launch it then tries to make you buy the full version. AVOID!!
