Mount Whirl

Mount Whirl is the second world the player will encounter in most runs, (They might do World 2 Darkness) featuring many Spinners and tall, rotating walls, hence the name of the world. The world consists of Weak, Average (and their 2.0 counterpart), Strong (and their 2.0 counterpart), Ghost (and their 2.0 counterpart), Hunter, Gunner (including their 2.0 counterpart), and Tornado Droids.

Environment
Mount Whirl has a pale, beige, cobblestone path with grey slate walls. Despite its name, Mount Whirl does not resemble a mountain nor a volcano.

Mount Whirl features many Spinners, long beams that are almost always spinning around. Spinners can spin very fast, but they can be slowed down by droids and players. However, if spinners are slowed down/stopped, they will begin to accelerate if nothing is blocking the way. Most spinners are located on the ground, however, some may be located on the walls, and spin about a horizontal axis instead (aka: the pivot is horizontal).

Green spinners rotate counterclockwise; red spinners rotate clockwise (viewed from above). Spinner heights may vary among three levels of heights, and they can stack on top of one another to form a tower of spinners.

Spinning walls can also be encountered, some with holes in them. Walls spin much slower than spinners, and similarly to spinners will accelerate their rotation if they are slowed down and then left alone.

Aside from that, rocks may also be seen.

The world has no environmental hazards. However, the spinners could push droids into your face or push you into droids' faces, so you still need to take caution when around them.

Trivia

 * The rotation direction of spinners and spinning walls can be changed by pushing them the opposite way, but when left alone they will eventually return to their original direction of rotation.
 * It is one of the few worlds to lack environmental hazards.
 * Mount Whirl is a lot people's least favorite world.
 * This, Mechtropolis and The Darkness are the only worlds to lack environmental hazards.
 * This is assuming you do not count the Turrets in Mechtropolis as an environmental hazard.
 * The song that plays in this world is called Danny Baranowsky(?) - Forest Funk.
