That's not to say the whole experience is just text on a screen. There are also a few mini-games and pictures as well. These mini-games are very simple in their visual design. Games like horse races involve small sprites on the screen and others like the hidden object aspects are super simple, but use the iPhone's pinch-and-zoom system.
While there are the aforementioned mini-games, a majority of the game's visuals are the text of the book you are reading. I found the default size to be just a bit too small, but it is really easy to adjust not only the font size, but also which font is being used. Occasional pictures break up the text, and these are fairly good, but nothing to get worked up over.
The App's audio is a combination of background music that starts off with a rather Western twang, but calms down a bit as the song goes on, and various sounds that are activated when tapping certain words on the pages. Nothing too outrageous here, but I'm sure it helps to keep the younger, target audience engaged.
