I've recently gotten this game via Steam, and have been playing it for a few days now. I've noticed the commentators seem a bit... lacking in their awareness of things happening. I think it would be a good idea and a fairly easy one to add lines of dialogue in response to the player doing these things:
-Attacking/destroying the repair drones
-Shooting the bow at the commentators/the Emperor/ the crowd
-Attempting to attack the Upgrade Bot/The screens in the Upgrade Room/The trophies in the Upgrade Room
-Destroying one of your own clones
Or various other things, if others can think of some.
