Bests & Worsts Reviews from Amazon

I removed the option to use one click from all my devices BUT I just learned that does NOT matter if you have an Amazon gift card on your Amazon account!! One click WILL STILL go through! Well obviously just like the people on here my grandson saw this and purchased in error. I did hear him play it for about 3 minutes. Not an app I'd purchase BUT little ones will no doubt, it's definitely advertised to get the kids attention. Also I have NEVER AND WOULD NEVER purchase ANY app for 13.88!!! there's no app that should cost that much ESPECIALLY THIS ONE!! Amazon should really remove the app from the store.
