So whenever I whip up or diagonal-up while on the ground my aim's stuck that way until I press left or right. Also the 1000 Blades crash go wherever I last aimed my whip.
Oh, and I seem to be able to cancel my whipping to another direction if I mash fast enough.
By the way, when are you going to implement a controller config screen, alongside a general options screen? Kinda sucks that I can't rebind my controls. That, and flexible resizing tends to mess with the aspect ratio.
