Nice Concept, But It's Not Ready to Submit
Maybe I just don't know what I'm doing, but I've tried this on two different headsets and the ball doesn't respond to my talking much at all. I got a little air for a while, but I don't see how the game can really be played like this.
I also say the game isn't ready for release because of its shoddy design - there's no menu of any kind, and the title/instruction page you have doesn't explain much.
I really like this concept; I haven't seen anyone really utilize microphones recently. Keep working on it, and maybe get someone to help you out with some menus, etc.
