Wow, this link is important to you, follow the rabbit.

I love the use of particles in BRAID… it is amazing, and the art is certainly unique. Its main asset is not its visual execution, but its selection of animation. The character is looking a bit up, not just forward, as if he’s introspective. Tim looks constantly concerned with something, loosening his tie, slightly frowning; as if he’s thinking about arriving somewhere on-time. Also, every time he gets hurt, it looks as if he took the punch that killed Houdini poorly… It looks painful!

Anyways, follow that link
