Story
Bad guy put a curse to the heroine and now she has to hunt him down to dispel it. What do I think of the story? Serviceable. I mean, it's an eroge, story shouldn't be a priority, but it's a nice addition.
Gameplay
Turn-based RPG Maker combat. Oddly, only the heroine has skill tree progression while the her companions already have all of their skills from the moment they join your party. Missed opportunity if you ask me. Since I'm a fan of turn-based RPGs, I might be a bit biased in saying that it has one of the better balancing in terms of difficulty and progression.
There is a difficulty spike in the bonus content found after beating the main story, but that's to be expected in JRPGs where optional encounters are somehow times more difficult than the main story itself. If can't be bothered with the gameplay, just pick the "Casual" difficulty and you can basically steamroll your way through the combat while unlocking the events. There is even an item that you could use to intentionally lose a battle just to see the defeat scenes.
Art Style
If you like mature women with... substantial body proportions (especially when the heroine is pregnant) then this game is you. While there are other female characters that can join you later on in what I'd like to call "the bonus chapter" after the main story is completed, they don't have varied outfits and scenes like the heroine do.
Hentai
What we're all here for, surely. Unless you're that weird guy who plays it solely for the gameplay for some reason.
Game is mainly focused on the heroine, a 31-year old mature women with not-so-small assets. Like I said before, there are female companions later on but they're just that: companions. I don't follow the news that the developer might put out (because I can't read Japanese), but who knows if they're planning on patching the game to add varied scenes and outfit for the other characters or make sequel focusing on the adventures of the heroine and her female friends (rather than the male ones to you come across in this game).
What's most prominent here is also the pregnancy system. The heroine can get impregnated and even give birth; and not just to human babies. You can even acquire two skills: one that allows you to ensure fertilization 100% of the time, and the other one that allows you to give birth on the spot instead of having to visit a hospital (you can even give birth mid-battle!). And there is no time limit either, as the heroine can still function normally while still having a bun in the oven.
I have played previous games by this particular dev and while they do have pregnancy content, all of them are tied to endings. I'm guessing the devs integrated pregnancy content right into the gameplay itself to make up for all of the countless blue balls that they caused.
TLDR
You like tall women with big assets?
You like to see her belly well up?
You only care about the heroine and no other girls?
Good. Then I think you should give this game a try.
Game Versions & Translation
Oh no.
Here's the big problem.
As of the moment of this writing, I don't think the original poster of the thread has updated it with additional links pointing out the download of a proper finished version of the game (in my case, I downloaded v1.02; I think a guy named Daedroth shared a link somewhere). While it is the raw Japanese version, it is also the most stable as I have tried other MTL versions that other people shared and in the process of said translation I think it might have broken the game.
How broken? Well one version has problems in loading images, preventing you from entering specific maps if said map is dependent on the image. Another version broke the skill tree so that you could not acquire skills properly. Yet another one broke events that should have triggered in order to proceed with the main story. I even had on instance in where a door to a building instead led into a completely different building entirely, locking me out of the intended interior of the former.
"Oh no, but I can't read Japanese!"
Yes, well, me neither.
The solution is to just machine translate the game yourself with tools such as MTool by AdventCirno (look it up, it's pretty neat). Just follow the instructions or search for guides on YouTube if you're confused and you should be able to understand what the game is trying to tell you (just enough to not get lost, anyway).
