When I heard there was a game from Dr. Kawashima on the App Store I downloaded it immediately without even checking the reviews because of the good experiences I've had with the brain training series on the DS/3DS. This game is just not functional at least on an iPhone 6 plus. It doesn't seem to be displaying correctly. To make one of the buttons work I have to tap below it (directly above a different button actually) and the button make the dialogue that asks you to enter your name does not work at all. There is no point in the screen I can tap to make the button work. I am sure the content of the app is good enough, but it is not currently working on iPhone 6 plus.
