Ya it is because we ran out of time. We have a version with sounds now but we didn't upload it as the rules said we can't add anything extra to the game and are allowed only to fix bugs. We can upload the version with sounds if you say so.
You can add am updated build but it has to be clearly delineated from the version for judging - at least this is what I've seen others do. Afraid I'm honour-bound to judge the version completed before the deadline, but no reason why other players can't enjoy the updated edition! :-)
