Another corridor run, this one is extremely similar to the Eternal Fire/Menacing Underworld pair of levels. The biggest difference is that the aforementioned pair is interconnected by a series of rooms between the two corridors. This level is interconnected by a series of small corridors. As the corridors are smaller than rooms, this allows for the map to squeeze a couple rooms in between the corridors.
I also forgot to go back and collect the Yellow Armor and Quad Damage. Well, you know where they are, and I didn't need them anyway.
