Hey! I’m not affiliated with the guys behind Blocksy, just a happy user. To comment on your issue, its my experience that Blocksy automatically reduces the amount of menu items when there is not enough room.
I suggest you reduce the amounts of menu items, their length, the font type (choose a narrow font), and test on iPad screen dimensions (1024*768) in your browsers inspect tool, to experience how users on those devices will see your website..
With menu item labes that long, only 4 menu items will be available:

It’s hard I know to rethink menu labels, but a tighter menu is your best option.
