Mario Builder V11-4 - Mario's Adventure Showcase - World 6 

Already has. It’s in the comments of their most recent community post.

It’s in the reply to the commenter purplwithnoe in that community post.

Eventually in the close future the download link will be placed inside any of the video description that has the Mario Builder - Mario's Adventure Title in it so it will be much more easier to find for anyone to play with, it's just currently not there yet due to still being in the testing phase if everything works as it should.

@@Mynti_Dragon Oh, Thank you very much!

@@bossyretromakeri am very glad to hear that, i thought it would never release to the public.
