Try to name or match shapes using only audio feedback.

You can explore each of the shapes in the main menu option, EXPLORE ALL SHAPES.
For each shape, the game will announce the shape, and then you can explore the screen to find that shape. As your finger moves around on the screen, you will hear the location sound.
When your finger touches the shape, you will hear musical note "A".

Most of the shapes are solid, so you hear the musical note anywhere you touch on that shape.
