FruitSmoothie from Linemarvel here. Been testing the game out for quite a while and I have to say that it's already well above most the things posted here, and I'm not even done with a playthrough yet (At plants) I have no idea how much you're willing to alter or what you plan for the future, so I'm just posting some observations and ideas I have, take them or leave them, as I said, I think this game is already far above most of what's posted here so I'll be continuing to play it for quite a while, waiting for updates and such, regardless of whether or not you add anything I'm mentioning.
I found myself testing all the girls through the first couple of scenes to see which I'd rather play as, although some of the dialog is great, mainly the sex descriptions, some of the girls I found to be a little bland and a bit too stereotypical to their starting description with their speech. Like one of the girls is afraid of men and she's saying things like "No, I dislike men, leave me alone, etc", when a man tries to force her, just a bit too obvious for the dialog. Even if she's afraid of men, or one of the girls is a royal knight or nun or something, it's not like they'd follow it to the teeth, pointing it out with their vocabulary constantly. You could show a more subtle kind of disgust towards it maybe? Afraid of men and it'd show up even in non sex dialog, kinda making it seem like she's being raped before it even happens, you know? She'd shy away from men, wouldn't be willing to flirt (Unless maybe extreme purity failure, that she could flirt with that one guard bugged me.) with men, etc. The same could go for normal girls, maybe they'd be willing to flirt with men but not woman in the game immediately, sexual preferences.
What somebody thinks about a situation in general and what they actually say when they're in it are quite different, having a phobia of men isn't her personality, just a quirk added to it. She can still be strong willed or weak, pretend to be fine with it to save her sanity or go ballistic, plenty of options for her dialog. All that gets into character development and I know that's a delicate subject, they're your characters after all to do with as you please
I can only really talk about that girls personality because she's who I chose to play as past the first scenes, I wanted to see how the whole male phobia thing worked out while she was being forced into encounters with them.
Next is the npcs and items ingame, it could just be because I personally spent a lot of time in rpg maker playing dozens of games and attempting to create my own that I'm realllly not fond of the default sprites and characters, I had to see them for weeks during that period so they kinda bug me now, it's pretty easy to find custom sprites on forums for rpg maker, but I guess that comes down to preference, and I know you already have the girls cg's done so changing them would probably be a huge hassle. But if you ever considered improving your backgrounds, finding new user made sprites for all the items would do wonders for your game. There's tonssss of variations for every item and completely new items you could download and use, it'd certainly add a nice uniqueness I think because most people don't bother to edit the defaults. It wouldn't be too difficult to change the items like chests and bookcases and floors, you just save all the new items in the old slots and they'd just appear where the defaults were all placed.
Well that's all I have for now, will continue testing later! Oh and I haven't gone through all the pages here so I'm not sure if there's a gallery to be unlocked, I didn't see it mentioned on the front page or the last few recent ones, I sure hope there is. As I said, I spent weeks trying to create my own games so I applaud your progress so far, even though rpg maker makes things a lot easier than building a game from scratch, I know it's still hell to deal with and takes a lot of dedication to stick with. P.S: Love that the cg's are all mostly different for each girl, actually giving a reason for multiple playthroughs beyond just skills and item differences is amazing. I can already see spending about as much time playing this on a finished version to test different girls as I spent on Legend of Queen Opala, probably my favorite user made rpg.
If you read all this, props, and thank you, I get carried away
