TSA writes: Your voice is a powerful thing. With it you can express your emotions, your thoughts and ideas; you can change peoples perceptions, and challenge societal wrongs; you can create music and rhythm with it through poetry and song. One Hand Clapping gives you something new to do with it, as you use your voice to control a video game, leading your avatar across a colourful 2D world. Its a unique experience.
