Day 2 (or later): Police Station mirror responses swapped
it actually doesn't matter, both have Gabriel talking into the mirror so I guess one was just picked
Well, I don't want to be too stubborn for such a minor detail, but for what it's worth, here's my case for why the responses would make more sense the other way around.
First of all, I went back and checked the original game and it's opposite of the remake.
Here's how it works in the original:USE MIRROR
The narrator says, "The mirror reflects. That's all it does."
TALK TO MIRROR
Gabriel says, "Mirror, mirror, on the wall. Who's . . . oh, never mind. I already know."
(I captured and uploaded
an unlisted video to YouTube so you can quickly see the relevant portion of the original game.)
Here's how it currently works in the remake:USE MIRROR
Gabriel says, "Mirror, mirror, on the wall. Who's . . . oh, never mind. I already know."
TALK TO MIRROR
Gabriel checks his appearance in the mirror (he leans in toward the mirror and puts his fingers to his face) and says "Lookin' good, kid."
So I think the remake's responses should be swapped for these reasons:1) The "Mirror, mirror" response is of course a reference to the
talking mirror in Snow White, so it makes more sense for Gabriel to say this when Talk to Mirror is selected, like in the original game.
2) The animation of Gabriel checking his appearance in the mirror makes more sense when Use Mirror is selected. (It is true that Gabriel says "Lookin' good, kid" after he checks his appearance, but he is talking to himself, not the mirror, if you see what I mean.)
Day 4: Gran lip movement missing
Gran's lips only didn't move for "veau" of "Marie Laveau" but it was consistent
reported, thanks!
For me, Gran's lips don't move for the entire line
"Marie Laveau... oh, of course! She was that Voodoo woman, wasn't she?" It's worth noting that while Gran's lips don't move, her expressions (blinking, eyebrow raise, etc.) do play during this line.
Her lips begin to move starting with the line
"She preyed on people's fears and superstitions, is what I think..."I seem to be having some trouble with Fraps at the moment so I am sorry I cannot capture a video for you like I did from DosBox for the original game. If you feel a video would provide useful info, I can try again later to fix whatever broke in Fraps (or install Bandicam as an alternative), but it's late at night now and I wanted to get you a prompt response before I go to sleep.

I've been running the game in a 1280x960 window with Unity's graphics quality setting set to Simple. My computer's hardware details are in my previous post.
(If you're testing in the dev environment and not in a previously released build, maybe the lip movements were mostly restored by a team member already for the upcoming patch but the "veau" of "Laveau" was missed?)
Day 6: Bayou cutscene speech bubble missing
this has been confirmed happening only in 4:3 resolution and has been corrected for next version, thanks
Sounds good. I have indeed been running the game in 4:3 resolution (specifically 1280x960) so that's consistent with what you found.
Day 9: Snake mound redundant hotspots
the hotspots in the snake mound are fine in both resolutions we support (4:3 and 16:9)
if you have a way of triggering them, let us know the exact steps
I tried again and wasn't able to reproduce this bug. Unfortunately, I didn't take a screenshot at the time and don't recall doing anything unusual that would give a hint of what the repro conditions might be. Unless someone else also reports this we can consider it a fluke. Sorry for any false alarm.

Thanks again for looking into these!
