I'm remembering now that the Crouching Block was the first bit of animation I did for Ms. Fortune and this move was the last bit I worked on before moving to Painwheel. This WAS the first time I witnessed how um…bloody, her moves can be. When her first gameplay video came out, I was shocked!

Ms. Fortune's the toughest opponent in the game, but I can never be mad when I lose to her, because she always congratulates herself as displayed.
