SPOILERS BELOW
Hey there, Mr. Vertigo. It's been a while since I played Crimson high last so I decided to come back to it and now share my thoughts again.
I'll start with a couple of the more important things:
Firstly, I forgot to mention this last time but I really wish you would find another model for the boar. To put it in a politically correct way: it's not a good look for you to use the current one.
Secondly, I have to say that I personally am not a fan of the "floating tongue" thing in the Suzu scene. I really don't like detached or invisible body parts during sex scenes. If it were up to me, I'd leave the scene as is and just remove the tongue or shoot it from a different angle. Obviously, that's just my opinion and you have others to cater to, as well as your own preferences, but I thought there's no harm in sharing it.
Aside from that, there's a bit of inconsistency with lightning. There was a least one scene where it's visibly nighttime but then you switch to that "blurry apartment image" that displays daylight, possibly even switching back to night again afterwards. I believe this happens more than once and possibly in a location other than Ren's apartment as well.
I have to say that this whole hotel thing and everything that it(or whatever pronoun is preferred) encompasses feels overly convenient. First it was Inaywin's watch that seemed a bit too much and now the hotel. I'm sure you will eventually explain everything and provide a good reasoning, however, I can't help but feel that we're dealing with a not-so-distant relative of "plot armor" here.
This is a minor detail, but when Miko walks on Ren and Touka talking in the library, she seems to be wearing shorts or something under her skirt? Not sure what's up with that; later when she's lying on Ren's bed, there are no shorts.
I like that you keep changing hairstyles, this needs to be more common outside of your game. I must comment though, that Aki's recent change doesn't suit her in my opinion. Not talking about my personal preference for hairstyles, just what I think fits the character. What she had was "very her", while the braided version I feel like does not match her personality. Might be wrong though. Fun fact(hopefully): I had just recently learned that this new one you gave her is known as "dead mom hairstyle". Naturally, it doesn't apply to this case, since Aki neither is a mother nor is going to die(most likely).
Speaking of Aki; her stating that Ren could be the only man on the planet who can have sex with a vampire seems oddly definitive? I might be incorrect, but the whole thing was descriptive of specifically humans, not other myths(not that we see too many male myths). It also implies there are no male human SECS workers who would also posses the pills. I suppose "man" can be interpreted as "human male", but I feel like it should be clarified better?
I'm glad Nene finally showed her face, but in a way it was a bit disappointing. I was hoping for some sort of "monster-y" mouth. Instead, she just ended up... very cute. Which is not a bad thing, but felt somewhat anticlimactic.
By the way, I really like that image of a dream(?) a the end, that is not quite unlike how Suzu described her dream. I wonder if the cast selection is relevant to the story...
I guess I'll end it here, it has become quite an essay.
I loved the new content as well as replaying everything old from the beginning! Keep up the great work on this masterpiece of a game!
P.S.
Did you do this on purpose?
