You're pretty caught up on exact wording there. If it helps, the developer was bored by the ease of the rest of Rondo, thus he made a quick, ruthless stage without even pretending to unify or justify it visually. The joke is that the stage made it into the game. I don't know why that isn't hilarious.
Also come on, I already explained my stance. I find the stage fascinating by the mere fact that it exists, the story surrounding its creation, and how it's pretty balls-hard to play through (this is not a cry for Rondo to be more difficult in general). And yes, it being an alternate choice to the "proper" stage is crucial, as well. It's awful on paper, but I like it in context, as an aside and a bit of history.
I dunno if that's addressed to me, but what's this about Dracula X? I only joked how I like Peke more than it (which is true).
