I'm going to disagree with everyone here and say that this level is a classic just like The Nightmare. It has a similar level of popularity (widely regarded as one of the easiest demons), and I really don't think it's all that bad — in fact, some of the unique design choices (such as the portal deco) help the level stand out from other levels from its era. The only mildly annoying thing about it is that one bounce pad that got broken due to a change in how the ball handles ceiling collisions, but that's pretty easy to get around.
