I wonder why the "creature" representing Milla's kids in Milla's Nightmare Room is the same creature that sucks you into the underworld two times in "The Milkman Conspiracy". Were the programmers just cutting corners and so they re-used a pre-existing creature so they didn't have to come up with a new creature?
And why have those two underground fights at all in "The Milkman Conspiracy"? They didn't seem to have anything to do with the rest of Boyd's mental world. It's like they're just tacked on. Did the programmers think the level was too easy so they tossed in two more fights along the way? Doesn't make much sense to me...
