Okay my notes so far with the demo.
Sisters looks.
It's important to stay consistent with your character appearances. ( This could come down to personal preference as I came to really like the look for Velvet in the first one and it's what drew me to the game, try to keep it from being too much of a rant).
Velvet changes hairstyle, hair color and loses her glasses makes her look like a different person. Bit too much all at once.
Ashley Hair style change and just her facial expressions make her look different.
The hairstyles all look too similar between all three now, long and straight. Losing the personality the original had between the three.
Add all this to a Demo that starts before any of the other events in the first part and it feels more like a reboot with new actors then an actual part 2.
Clipping issue with clothing
Conversation with Gabriel, his shirt keeps clipping through his undershirt. The clothing even looks like it's not stitched together.
Velvet has way too much clipping going on when showing anything below her chest. Clips with underwear, sweater, skirt in every image.
There are minor instances of tiny sections of clipping with Scarlet in one photo and Ashley's clothing in other photos as well. Mostly it's Ashley's top having tiny little spots every few photos. Easy enough to fix in Photoshop.
Visuals
Images are over exposed. You lose any definition in bright areas in scenes, especially the white shirts. They just come off as almost a solid color
Story side
Not much to say, not a lot going on. Introducing all the characters again is a bit weird for a part 2 of something. Having to choose the protagonist and set relationships again makes it feel like we are starting over again instead of continuing with our previous choices. And from looking at the code the only choice we may be carrying over ( tho it doesn't load a save right now) is if we join the corporation or not. I suspect we are just going to choose in dialogue later on instead of loading a save. Like the choice of protagonist.
Conclusion
Having to reselect the protagonist and the relationships from previous game, the change of appearance to the sisters. The clipping problems present in a fair amount of scenes , It feels at the moment more like a rushed reboot of the previous game rather then a continuation of the game we played before.
EDIT: also to note, (feel like I'm going into rant territory) if changing the appearance of the sisters is just for the time skip to a earlier time then it will lead to just unnecessary confusion of some of the new and old players. Along with inviting the normal "I prefer them this way not that way" discourse that you will have to deal with now.
