As decent as the animations look and how kinky it can kinda get, I can't in good conscience give this a better score. I've only completed grinding with the redhead so there may be differences between the other two and her, but it's doesn't fix the issue.
There is a lot of animation/model clipping, doing any vaginal penetration in an outfit causes the model to clip into and out of the panties, and it looks nice without panties sure but stuff like the bondage outfit looks nice and in order to wear the outfit you have to deal with the clipping.
The 'customization options' are way too similar between all three. Aside from color variations in shared outfits and a notable difference between bondage/dress outfits that are acquired at the same level, there is somehow too little variation and too much. Why add the option to make all 3 of them white rather than have one be a gyaru or something, especially since all of them are pale skinned already. All three get the same dark elf skin, cat ears, demon horns, and a lust tattoo, but as I said before there are actual differences in regards to the bondage tier (where red head gets a corset, young blonde gets a bunny outfit, and the last gets a skimpy non-bondage dress). It would have been neater if one of them had gotten demon stuff and one of them got stuff like the cat ears while the other got something else, just having a theme for them rather than "they can all be demons with the exact same horn shape".
The game chugs performance wise and the whole "take a minute to load the night then reload the game and show the game company after every night" is what really drags the game time and grind. I noted in a post in the thread that it took me from 3-6 hours to get the red-head up and swapping to other girls (both are under 20 affection still). The load times are bad enough and the gameplay itself isn't anything that special, but with a hurrying attitude you can complete each night in about 5 minutes if you count loading and such, the majority of which will be the title and loading.
Speaking of gameplay/time to complete each night, it's good to get to that now: foreplay is awful. People noted that it's worst with the redhead due to her positioning but it's also not great in general because it's just a dull mechanic. You can't take initiative, you get no good buildup like in other games where you touch characters and the girls climax/squirt after every touch which is weird when they are still in clothes. If you enter a night at max lust, you'll start with sex and you won't need to do foreplay to unlock options for the night... but at the same time you still need to do foreplay to get affection for the night even though you were already going at it. As for sex itself, it looks great (aside from clipping) but the timer loop keeps you looking for random popups rather than enjoying the moment which leads to the big issue... the grind.
Let's say it takes you 3-5 minutes to complete a night with max foreplay and affection gain. You can only gain as much affection though as the character's starting lust, meaning you'll get basically no points if she's only got one star at the start of the night, you cannot modify this in any way in the game without cheating. This means a completionist should jump to the highest lust character each time, only changing once one is done or to catch one up with the others. 5 star lust does not equal a full level of affection however, so I'm going to argue that it takes a minimum of 1.5-2 attempts per affection level. This means that in order to get 23/24 affection, you need to grind over 40 times per character. On the low end, assuming you do everything in 3 minutes with fast loading times and you're paying attention, it takes about 120 minutes assuming you only select one girl each time (which you shouldn't unless she's your true waifu, because the characters will have low lust periods where it's better to grind another).
Every night is basically the same as well except you get less options at random, depending on her lust she might not be up for some sex acts and it seems to be random (like missionary B will be available, but not missionary A), if you don't understand what they are saying then each night ends with them saying stuff for another few seconds that seems to repeat quite often. There is no story mode, if they do talk it's not made clear on if this is one dude with his harem of if you are cheating on 3 random women.
If you're able to cheat and get a full save going then it's probably a 4 or so, like I said the animations are pretty good and the sex acts do have some variations between the three characters in terms of body position and climaxes, but to actually sit and play this game and grind in it? I had to pull up another computer and watched youtube for most of my play time because I couldn't leave the game open while watching on this computer, and it still took too long.
