Wow, very impresive.
I would love to try out for the voice acting, I've done a lot of acting, but not mainly voice acting. Recently I got 30/30 from a drama examiner for my part in a play "Pass it on" where I played a prick in the army.
One problem, my microsoft office is messed up, I can recieve e-mails..but not send. If I could PM you my details, or if you know of anyway I can fix my office would be much appreciated. I could use my fathers computer but that could complicate things.
I'm also younger than your characters, but I can try to sound older.
Anyway, good luck with the game.
