Hi
I played the demo like three days ago and I must say, I really liked it. The atmosphere is great, you really do feel a bit lost and confused, as Nemo would be. Lien's story felt a bit empty though. With Nemo's being so full of mysteries and everything, it felt hard getting into Lien's and I mostly just wanted to go back to Nemo.
I haven't seen absolutely everything yet, but I like how choices feel like you can get events that can be very different, like when you can get locked up in the cell and you can feel it affects Nemo
Now about moving around. It's fine, but I found it hard because of the way you sometimes have to move. Mostly when you leave the staircase area but want to go to the grey/blue door. It's confusing to have to turn around and not even finding yourself in the same area you were in.
Characters seem fine, they all are a bit weird, but they're fine, I managed to find at least three I kinda liked (Elias and Yakov are great)
About the art. It looks great, but I'm disturbed by Oliver who's just anatomically weird. If it was intentional to give a fat neck and a fat belly but otherwise making him thin, great, I guess, but he's too weird for me to be able to look at him (it's mostly the neck though, really, since the face is what you look atat the most).
Sometimes necks are too long too, such as when Nemo is wet (and I think even with his new uniform). Those are just some mistakes I see and they're only disturbing because they're inconsistent (like if necks were always long, I'd be able to not think about it)
About the opening, too. I find it a bit fast. You present the characters two by two but I barely have the time to look at one and his name before they're both gone.
The menu music is great though
Otherwise I look forward to the game's development as the story seems interesting and I do hope it holds up to my expectations.
Good luck to you
