I thought "palatial" would pertain to the palates (aka insides of the mouth) :D And for "ambulatory" I tried all kinds of things related to ambulances, hospitals, sanatoriums... :D
The only ones I didn't get were avuncular and littoral, had never heard of them. Stared at them for 2 of the 2.5 minutes I had left, but wasn't getting anywhere so clicked give up.
Gubernatorial I also had never heard of, but that one was decipherable (ow and for ducal, I migghht have heard of it, not sure but duke was obvious)
Not all that hard in my opinion (and not a native speaker) but fun to do :)
And yea for palatial I was first thinking of palatal, so initially tried palate, taste, before realising. It was the only one where I did not put the correct answer immediately. Ferric had me thinking of feral for a (mili)second though.
