On some of our games, on Ipad, you can tap on the PLAY button, and the music starts, then you tap it again and the PLAY button performs the function of starting the game. So it's taking two taps to start the game.
The first tap, no matter where you tap on the screen whether it is in some space on the background, on on the PLAY button itself, will only trigger the music to start.
On some of the games, also on Ipad this is not an issue, one tap on the PLAY is enough to start the game.
On Iphone, desktop, android it is also fine, single tap on PLAY starts the game.
