The game starts off with a very simple premise, and honestly that's enough: Huniepop but with Daz3D renders. And it delivers on that front fairly well, except for a few misteps.
The game is WAY TOO grindy. Whenever you succeed in a puzzle, the amount of points you have to get during the next "date" increases. The problem is that this isn't girl specific: even if it's only your first date with a girl, if you're already finished with others, you'll have to make'em drink like a 60 year old half-blind alcoholic to lower the points required. EXCEPT for some reason - which I'll assume is a bug since the prince tag stays a static 15$ - the drinks are getting more and more expensive, the higher level your puzzle skills are. And even if you have the money for them, for SOME REASON the dev decided that's it's a good idea to randomize the items in the shop every time you open it, so if you're looking for something specific, you might have to open the shop again, and again, and again... until you get the amount you were looking for. So unless you spend HOURS talking to them over and over so you can level up the points you get for matching colors, you'll have to play the puzzles knowing that you'll lose, just so you'll get some money to buy drinks - and even if you did all that, RNGzus can screw you over.
You get 3 pictures with each girl plus a total of three scenes, one of which is foreplay. The animations are sort of clunky and the camera is a little awkward during the sex scenes, but other than that, it's servicable. The english during the sex scenes is more broken than the time perception of a dyschronometria patient, but it's just the most generic porn talk anyway so who cares. The main question is, is it worth putting yourself through all those hours of grind? If you like these types of games, then yes. If you're only here for the CGs, definitely not, especially since you can't even rewatch the scenes you've already unlucked for a girl until you max her out.
-------------------------------------
And then some nitpicking, mainly for the dev: other than the grind, my main problem is the UI. I might be dumb as a rock, but it took me 4 hours of gameplay to realize that the half visible demonic circle on top of the screen brings out YOUR PHONE, which contains your inventory... your game settings... the girls' stats... everything basically. A simple phone icon would've sufficed, and I'd also recommend moving the settings somewhere else, possibly to the main menu as well since I usually want to adjust the sound settings when I start a game. Here, I could only do that after the prologue, since the menu is only home to the classic NEW - LOAD - EXIT triumvirate. Advancing the day when opening the shops also serves no purpose since there's no day limit or anything... which I was sort of glad about since otherwise the shop RNG would've ruined the game. It also feels a lot like the girls' models were made with 0 care about what's written in the game about their bust size - or the other way around. I'm pretty sure Hecate is not an E cup... For the skills there's no indication or anything telling you that skills in every column can only be equiped in their specific slot, and you don't know their costs until you equip a few and realize the pattern. It would've also been good if in the shop the game showed me if I already own a few copies of an item.
These are just small things which were more like mere annoyances at best, but they do add up, so I hope the dev improves on these as well for his next project, because other than these and the grindiness, the game delivers on what it promises and I'm looking forward to whatever the developer's next project is.
