Piano notes music game 09

After a lot of research, I realized that the software I was looking for just didn't exist, so I decided to create it myself. Five months later... Piano Is Fun was born!
I started out by searching for note learning software but the only programs I found were monotonous drills, You know the ones - where a note appears and you just click on its name. I knew my nephew would find these games dull and boring. What I was really wanted was a program that would:
Introduce the notes gradually
Teach both the note names and where to find the notes on the piano keyboard
Clearly explain the difference between the Treble and Bass clef notes
Allow me to select which notes to practice
Use bright and colorful animation
Be so much fun that my nephew would keep coming back for more
