| This level is a major plot point!
This level is a major level in the game. After you finish the level, you may be able to access other characters, minigames, and tunnels. Most of them also include a cutscene.
Note: Since you must use the Student in this tunnel, she will be the only suggested character.
In this level, you can see that there are lots of medium size platforms, scattered around the level, with Conveyor levels being present.
The gaps between platforms are far. After you jump off the edge of one of them, use the skill and float back to the air (Note: Don't float up too high, you may accidentally flip to the ceiling), and find a landing place. Locate it, and prepare to land.
The platforms are scattered around, so be sure that you know which platform you are going to land next, and proceed to it. You can also try to maneuver along the different paths of the platform.
There is a cutscene that featured in this level. More information on this cutscene can be found here.
Morning Hypothesis (Part 4) Edit
The Student is in Level C-4, and she is trying to talk to the tunnel, or the authorities, whatever. She says, "Are you still there? Cause we need to talk." She gets no response, and is annoyed at how they already lost track of her. Then she thinks that the person might just be rude.
