No really, this was extremely cool.
The style is awesome. I like the semi-noir feel, with every character getting one color, and then using different shades of that color to make them lifelike. Animation is very smooth, apart from some minor hijinks, like when he's threatening the orange kid, the fists look a bit jerky.
The story was very interesting. Quite the simple, maybe a tad cliche. I liked the twist, though.
Voice acting is pretty good. GG doesn't have the enthusiasm needed, and there was one microphone that was a tad below par, but nothing too bad.
