A really nice take on the theme. I enjoyed playing this quite a bit, and the music and art was great too. Ended up getting murdered by two of those toothy 5/4 bastards who spit at you from a distance (very cool death animation for the king!).
One thing that was unclear for a while was what the numbers indicated. I eventually figured out it's attack/HP, but it's not immediately clear, especially with the king's shield appearing in the same spot under his sprite.
But anyway, overall this was great. Fantastic work!
