we are the developers of PianoGame for iPhone, a free educational music game already in the AppStore since more than a year
We just completely updated the app, we changed the whole graphic, added some new features and we made it a universal app, now natively runs on iPad.
We would kindly ask to you a review, in order to help us to make it known.
It's absolutely FREE! and can download it at following link: PianoGame Free for iPhone, iPod touch, and iPad on the iTunes App Store
Thanking in advance, we wish you a Merry Christmas and an Happy New Year!
