So something even more interesting that I discovered after fiddling around with CE.
I found out that in order to get the "lustful" status for certain enemies, you actually need to have two sensitivity spots reach a total of 400 points. Obviously, this is locked behind a max cap of 150 per status in the current demo; but forcing the status cap beyond 150 for, per say, crotch and vagina, this can result in the flies and nest to showcase a lustful status. Setting the plant-related status to 200 also allows you to see a lustful status, and my GOD does she sound incredibly sultry.
Now, I still haven't been able to get the heat or lustful status for the crawler, BUT
I discovered that her eyes change colour with the parasite with the current forced parameters. I've been making sure that this isn't because of the plant haze overlay, but it seems to happen by random when the parasite reaches imminent. I'm able to get heat status with the parasite, which means I'm missing a body sensitivity; but it seems like these other parameters have not been added into the game as a working function.
