How to make the best custom navigation and menu

Dear community!

This is my example how to create an inspiring custom navigation and menu. 

I used:
- The custom buttons for jumping to the next/previous slide
- Help button
- A lot of layers to make the menu like a map

 

This course was the best eLearning solution in Russia in the previous year.

You can find below the movie about this course (video in russian, sorry).
See this project in the attachment.

Please enjoy it :)
