This is a very interesting and good game. I have downloaded this game many times but I never bored with this game. The most important thing is I have learned the piano very easily from this game. But the very bad disadvantage is it contains too much ads for everything. I can't do anything without an ad. This is becoming very bad with these ads. Do you not think when young children play it, they can learn bad things from this like sex. Plz do control of it.
