Stuck in Catacombs Level 2!
I can't seem to find my way out of Catacombs level 2. I get the three keys and then haven't been able to find where to go. I feel like I've walked through the entire level with both the blue and green lanterns and can't find a thing. Very frustrating!
So I've gone through the first part where you get the four levers to open the door to the left. Then gotten the blue and green lanterns further left. Go to the bottom where you must use both lanterns to get to one of the keys. Then I go to the top and use each lantern individually to get the two remaining keys ... now what?
