A cool take on the theme. I liked that it was a physical table that you were turning, and having three roles split between two parties was a good way to add some extra variation.
When you have the gun, the enemies just immediately run away and disappear, which felt a bit disappointing. Maybe having all the enemies that was already in the area stay in the arena would have felt more like you were now hunting them? Otherwise you're just taking a few pot shots at the last fleeing ones and it's all over.
