This probably isn't a super common sentiment, but I have to say it. In addition to the many reasons this game is awesome, I really love how the skin is designed. It's not that leathery, plastic skin that most 3D games have. I really love the visible veins. Even the big games like Being a DIK don't have great character models like this. This dev just keeps slam dunking it.
And my lord, there's boob veins. I never thought I'd see the day. These are noticed, and extremely appreciated. This is one of my favorite things and is super rare.
