Why isn't this more popular!? – BRIO World - Railway Review

My son (3yr) loves this app. Plays it to the point where I have to take it away. But honestly it so I can play. Haha. It is a great app for the price. It's also a game that I feel he is also learning while having fun. It would be nice to have more options i.e. A all delete button or even a lock button.
