Shadow feature is really cool. It does pick up on your tendencies and habits. I could see the feature being a lot of fun to mess with going forward. Great job on that mode IG/MS.
Character select isn't initially that much smoother but after initial load it's noticeably snappier for me. Feels like it's really close to being optimal. I am not sure about stage load times yet but on first appearance they seem to be a second or two quicker. Still some lag upon pausing the game at times but it appears that the brightness/gamma blow out was possibly fixed or reduced.
Hisako classic is my favorite retro, not big on the accessories (outside of the pop outfit being fun.) I do wish she had a human skin option like the default skin does. Classic Cinder is exactly what you'd want classic Cinder to be. Hopefully die hard fans of the original are happy with that. Not big on his accessories.
Speaking of Cinder, his moves seem to be coming out a bit smoother now. Probably thanks to cleaning up some of his inputs.
ARIA is pretty fun to play, still getting the hang of using her assist and managing my health. She isn't a character I am initially enamored with but still a nice addition to the roster and I am sure others will like her play style. Her stage music, now that I have heard it in full, has some moments I enjoy but overall not my favorite of the bunch. Stage ultra is fun to see in person, the sound of the wind and impact help it. Hope we see more stage knock offs going forward (or added to some Season 1 stages.) Her inputs may need some cleaning up as well, her normal ultra command seems to 80% of the time come out as a body switch ender instead.
