Super Monkey Ball 2 - World 10 - Dr. Bad-Boon's Base

It wasn't enough for Dr. Bad-Boon to steal all of Aiai's bananas. He's created a giant ray gun from inside the space colony that will...make all bananas taste like curry forever! A banana that tastes like curry actually soundskind of interesting, but Aiai loves the way they taste. In his quest to maintain the status quo, Aiai somehow gets wind of this and goes into the room with the laser cannon. He seems to want to destroy the entire colony though...But it being a colony and all, doesn't that mean a lot of people (or monkeys) live here? Apparently, Aiai will not hesitate to commit genocide if it means he can punish Dr. Bad-Boon.

Go ahead, take a look at the World 9 background. There are what appear to be buildings, parks, and streets over there in the distance. There's a civilization in there, and Aiai plans to blow them all up.

Anyway, this particular set of stages is exclusive to the story mode--they do not appear in the Challenge Mode. (If you're wondering, the Expert stages in Challenge Mode end at Air Hockey.) I suppose you can call this beyond Expert. This set seems to place its difficulty mainly in its intricacy rather than precise timing. That is, you need to figure out a specific sequence of actions and perform them, and they tend to be quite long:

10-1 Training (8)
10-2 Gimmick (9)
10-3 Mountain (9)
10-4 Disorder (9)
10-5 3D Maze (8)
10-6 Labyrinth (9)
10-7 Postmodern (7)
10-8 Revolution (8)
10-9 Invisible (9)
10-10 Created By (6)
Average: 8.2

Training and Created By seem to be the only ones that don't fall into that category--they're plain old ordinary stages. All of the others need to be planned out in advance. Again, I played through all of these in Practice Mode, so I know what the answers are, but I'd like to bring up the ability to view the stage when you pause. You can change the angle and zoom in and out as you wish. There's no other group of stages where it's more important than this one. Well, you can't do that with Postmodern or Invisible, the former because it's set inside a building and the latter because, well, it's invisible!

Labyrinth is perhaps the most shining example of this. You've seen the maze sets of stages prior: Dynamic Maze in World 4, Flat Maze in World 9, and 3D Maze over here; Labyrinth is the last and definitely the toughest one to solve among them. The stage is a messy and perhaps intimidating conglomeration of ramps, tunnels, floors, and walls of varying colors, the different shades necessary to know what leads where. And there is exactly one path that will lead to the goal.
