Today I made Cat piano with Scratch

It was so difficult to program the piano.
You can look at my piano with clicking this.

My father helped me.
I took 2 days to finish this program.
The most difficult part was changing  the tone.
If you have your keyboard you are lucky, because you can play the piano with your keyboard.
If you don't have the keyboard you are still lucky, because you can still play with the piano with my program.
Good-bye everybody!!!!!
