Great app with great potential

Lots of information in a format thats great for kids and the quiz feature is excellent.
Similar colors make it a bit hard to distinguish between the images of Mercury, Venus and Mars. Quiz gives neat stickers which is a great idea to develop further, i hope these stickers can be seen and repositionned on a screen you could go back to event if you dont complete the entire quiz.
I would also prefer for any kid oriented app to contain no external links such as facebook, others games/adds, etc, or at least to have the option of removing them by using the ipods settings.
