I personally think the character looks like trash, aesthetically, but I know I'm in the minority. People seem to like his design. Seems grade-school edgelord in the worst way for me, and there's nothing coherent about his design at all. I guess that's kind of the point, or whatever, but it doesn't work for me.
Gameplay-wise, I didn't think that trailer was very good at all, and didn't show much of anything, to the point where I didn't even want to scour it for details.
They will definitely do a small character breakdown and upload it to Youtube. It won't be anything too crazy, but it will give a clearer indication of what kind of character archetype he's supposed to be.
