Bests & Worsts Reviews from Amazon

I have played this on my iPhone 5 for a couple months now and I love it! a friend who runs Android on her phone seemed to have different choices so I loaded it onto my Kindle Fire. So far it has been very 'buggy' in that I first watched it restart my kindle after installing and opening for the first time. Then after restarting the choices weren't showing. After another restart I tried to select a drawing to color and nothing happened. I removed the app and reinstalled -same thing! don't know what the problem is but I'm pretty disappointed...
