Mechanical

Mechanical is a Class 0 sub-difficulty of Unfailable.

Obsctales in this difficulty
You are thrown around really fast conveyors around from the entire floor until you reach the bottom. Even if you fall, you still get teleported to the Mechanical outside. Your walkspeed and jumppower is removed at this point, and you are going down the frame until you reach the bottom. When you reach the bottom of the outside, you end up in the roof of Mechanical. In the roof of Mechanical, there are what seems to be Automatic-difficulty stuff, but remember, your walkspeed and jumppower is removed. Once you touch the winpad, your walkspeed and jumppower go back to normal.

Continuing from this point
Go to Automatic.. I don't know why you're trying those unfailably easy difficulties.
