Aww, what a fancy cartoon this is. The lack of colors made it especially good. Ironically, it was quite colorful. I know about Norse mythology from those "'Thor" movies. The sea monsters were especially nice to see. It looked like it was raining marshmallows!
It was pretty uplifting. The main character kind of looked like he was made of Legos. The rest of his body really wasn't. I appreciate how much detail was put into the shading. The lines really stand out in something that lacks color.
