Katamari Vol. 1 injects situational gamer humor and in some places, deeper philosophical morals. It delves into the motives and personalities of the main characters while maintaining the essence and feel of the game franchise, despite developing a different art style.
It also offers exclusive commentary about the creation process from the creators. Alex, who likes to ponder the emotional side of things; and Ray, the goofy counterpart who frequently expresses his obsession for Ace.
There are also a couple pages with sketched panels as well as a section at the end including bonus art from promotional material to exclusive prints.
