This level requires short and medium jumps. Like the rest of this tunnel, the Runner is great here, and doesn't require an explanation. Just jump high and look for a landing place, then navigate your direction mid-jump. If you think you are about to miss the platform, consider to land on platforms on the walls instead. As for the Bunny, it can take a few short hops, which can increase its momentum and speed significantly, when you then jump, you will be able to skip a big chunk of the level. With the Pastafarian, there's still places where you need to jump, but there are a lot less gaps than with other characters, since there are quite some gaps filled up by the light bridge, though be careful that you don't jump on it easily, since it will destroy the light bridge instantly. When you beat this level, a cutscene is initiated.
Here is some information of the cutscene that featured in this level. More information on this cutscene can be found here.
After beating Level D-14, a cutscene will begin in Level D-12 showing a conversation between the Runner and the Gentleman. The Gentleman requests to rename a few tunnels due to uninformative names, which the Runner reluctantly allows. Then she runs back through the tunnel while the Gentleman considers the different factors needed to make a good name.
