A great app on several levels – My ABC Train Review

My 2.5 year old sons loves this app. First, it has trains! What boy doesn't love trains? The animations in each train car are great. There will be a letter, say a graffiti style capital D. The child can tap the letter to hear it's name. Then you slide open the train door and see a drum set. If you tap on the drums, there's a brief animation of the drums playing and lights flashing. Each letter of the alphabet has a similar animation. But why my boys like the most is the train engine. You can tap various parts of the train to see and hear different effects such as tapping the driver to see him ring the bell. My only suggestion would be to add some sort of alphabet index so you can skip to specific letters if you want. Otherwise I think it's a wonderful app that's very well designed.
