I'm having trouble with the control room.
I went through the tunnel, the rat stole the manhole-broom-key thing. I flipped the guard-shoot-the-target, he went to go collect more bullets. As he was collecting, I stole some bullets and threw it on the floor near the levers, stole his key, and couldn't flip the switch. Now I'm flipping the guy over constantly and I can't continue. What do I do now?
