I used earlier version of this app to keep kids occupied, it was simple and there wasn’t much they could mess up.
Now the in app purchases are offered every time you run out of bubbles (every ten seconds or so), and they are offered in a way that seems like part of the game to a kid.
It’s no longer an app I can just let a small child play on their own. Also it’s just plain annoying to offer purchases every ten seconds.
