Good game, WONT OPEN!!! – Bouncing Slime - Impossible Levels Review

It used to always open when I clicked on it. And sometimes when I clicked on it it would go to the first page where it says the logo and who made it, but then would go back to the home screen of my iPad. Now, I can't open it at all. I've tried resetting my iPad and even did the update and still won't open. I've had it for about a year now. It's a great game in always keeps me busy, but now I can't even open it?
