Looks like there is a collider missing in the last level. I am not complaining, this made the second to last step easier :) (I also know the legit solution so we cool)
I had a lot of fun playing it! My only critique is that when the king dies and you have to go thru the menu to open the last level, which is a tad annoying. Also the inclusion of pause is bizarre to me, since there isn't anything happening when you don't press any buttons.
