The art and presentation are excellent, but, the name is just next level wordplay XD The gameplay and what decides how and when you can pick up items is a bit rough and inconsistent, but, all in all a solid entry. Nice job!
"Dull & Han" = Dullahan, it's a creature from Irish Mythology, a headless horseman if you will, I believe it was considered to be a sort of equivalent of the grim reaper
