More links needed on the site

There are a lot of places where links would make the site munch easier to navigate. When navigating classmoji, I often find myself using an unintuitive combination of keeping multiple tabs open of different "subpages" of classmoji that cannot be normally reached from each other, and I often need to type in URLs directly.

- slides.classmoji.io (not a specific slideshow, but the gallery with all of them) is completely inaccessible though link navigation.

- pages.classmoji.io is also inaccessible, it doesn't have a way to escape back to the main page, and assignment descriptions/tutorials there aren't linked to on the assignments page. The assignments in the assignments page only links to github repositories.

- This feedback page is not currently reachable through normal navigation, clicking on the feedback page links to the github repo

If I may make a suggestion, I believe that the assignment page should prominently feature a link to the project's description, and that there should be a page's tab on the left.
