Good Idea, But Dont Buy
Our toddler daughter likes this and we bought the non ad version so that accidentally touching the ads wouldnt interrupt her. Now, the developers have put a "debug menu" right next to some of the items for her to touch and it interrupts the story more than the ads. Might as well stick with the free ad version.
