I have taken screenshots of everytime the girls had an event in the 1.1. version.
Their "Lewd Development" menu to be exact.
I also wrote in the titles of each picture, when the pictures takes place, such as Arika 1 (EV1).png where it is taken AFTER the event where Arika kisses Kurt, but before the sex scene (EV2). Makes it easier to follow.
The changes only happens AFTER an event, so even if you spot someone doing anything lewd, but it doesn't count as an event, the changes won't happen.
The changes are small to begin with, but once you reach a certain point (The one where Kurt is arrested, possibly the mid-point of the game) you see some changes, and not just an updated profile picture.
It is possible to turn up their sense of moral or turn down their lewdness by going into the Siren Church (the building to the left) and ask the goddess' blessing to help ONE of the girls per day, at daytime.
That blessing can only happen during Kurts' 20 day contract "parol" as he is still under "suspicion" for a crime he didn't commit.
I'm not certain, but these 'blessings' may have something to do with the alternate endings of the game (of how moral and/or lewd the girls are), as it is impossible to check at this point.
I didn't bother with the blessings for the screenshots, as the trials doesn't have those endings yet (except the vanilla one)
If you wish to compare their development, (for the trial version) or played the trial but skipped the development menu, it's down here.

Note: some of the translation are a bit off, such as "boys" become "girls" or calling "she" instead of "he".
Don't blame me for that.
Also, the SEV events (special events, I believe?) doesn't seem to change anything to their development, so those may not matter when the full game is out.
