Each slice should be 64x96 px. I'll check and see if there are any spacing issues when I can find the time. If you are using unity, you can edit the slices on Sprite Editor in the meanwhile.
Yeah thanks, much appreciated.
I am not using Unity, I work with Aseprite, and used 64 by 64 with padding of 32 in between,
at 64 by 96 without padding, I get the same behavior.
It seems to be very subtle 'missteps' frame by frame.
I could send you an animated gif of how it looks so you can see it.
