to me it just seems odd to have two menus right on top of each other that pretty much do the exact same thing....
I'd either eliminate the bar menu keeping to the hexmenu
or move the bar menu down into the footer of the site
currently the bar menu only has search and tiny portal which the hexmenu doesn't have
which you could put a search menu into the upper right of the header on the dark theme to fill in some space there and get rid of the button on the menu....
just a suggestion anyways

it is an interesting theme, I like the idea, not for me really but I could see it for specific niche forums
