Bought this for the steep price of 1.99, to me .99 would be fair. My son liked it, but kept going into game settings because the button is fairly large and located with all the learning buttons. If you could come up with a way to lock settings or move and kind of hide the button that would be an improvement. overall it was a neat app. If they fix the settings button and drop the selling price to .99 I would recommend and give five stars.
