Really neat idea! As the others have said, I would have preferred it to be a bit faster paced - but I guess I wouldn't be moving too quickly if I had a ball chained to my ankle! And I know you didn't make the sounds, but I just wanted to say that the choice for it to be mostly silent - save for the rattling of chains and the occasional roar - did wonders for the atmosphere. Stepping out into the colosseum for the first time and hearing that roar was genuinely daunting...
