Ive purchased almost all of the games this developer has put out, and my three and a half year old daughter loves them. However, the first thing I did on both my iPad and my iPod was turn OFF in app purchases so that my daughter (or myself) wouldnt be buying things without realizing it.
I think its great that they offer the game for free so you can try it out before you buy it - I hate buying an app only to discover I really dont like it at all. I also like that it works on both the iPad and the iPod - I always have my iPod on me, so it comes in handy to help distract my daughter when were at a restaurant or doctors office. The game is a good value because the puzzles change each time you launch them - so its not the same differences each time. I have recommended games from this developer to all of my friends who have small kids and an iPod/iPad. Keep up the good work :)
