You're kidnapped in your sleep by a powerful being, taken to their world, and they refuse to tell you exactly why they're keeping you there. What's worse is that they have a history of killing people simply because they're in a bad mood. So don't piss them off. But it there is a bright side... You're allowed to wander around the castle, and the rest of the Demon Lord's prisoners are all sexy girls. Each of them with their own interests, history, and needs. I'm sure you'll find a way to enjoy yourself...

It's quite solid. Writing is good. The situation is engaging. The main character is pretty likeable. He's quite fun to watch engage with the world, really. Other characters are also quite nice. The writing is also fairly good about taking the little tiny choices it gives you into account in the dialogue and character responses, as well as the information revealed. The porn itself is... decent koikatu work. Better than average, but fairly below the best it can be. The only real negative is that the MCs skin tone is identical to some of the other characters, so in some scenes his weiner kinda... blends into their faces and the like. There's not enough contrast, basically. The actual progression is pretty standard visual novel affair. You've got a stat to increase. It's not railroady. I call it 'linear sandbox' where you have a bunch of storylines, but can go about going down those lines. There's probably an actual term. I dunno it. All around. A good work, it's a persons genuine attempt to make an engaging piece of pornographic art. Worth experiencing. With a little refinement here and there I'd happily go 5/5.

First time trying out the game and it's looking decent as of v.0.18 It's not usual for me to try an unfinished game still in work progress, but it kinda catched my attention from the overview/images. I just like isekai games. - Story/gameplay: Short intro, before you being kidnapped into other world by magic. It never got clear why it happened thou, as it seems the demon lord woman which did it is completely capable of doing the job's done herself. Could it be because she just want you as a sex toy(doesn't looks like that's the case either for now). Is there a lack of males in this new world, since the MC never met another one. Nearby town's tailor and even blacksmith are women. While we got tons of h-scenes early on, on the other hand the story overall is still very shallow and undeveloped. There's a lot of questions with no answers yet, so we have to wait and see. - Characters: Since there's so many, whole 12 if i count them correctly uncluding ourself, ill point out only few. * MC: I like him a lot. We can take some wrong decisions which gonna kill him, but overall he's a nice guy, very adaptive to the situation he's in. I'm so glad he didn't got into some rebellious cringe macho stuff, because the naration and story are going very well as of now. * The demon lord: The main heroine of the story(well atleast for me), even thou we've seen not much of her. I like the fact she's taking a like to the MC and slowly warm up to him, giving him more freedom and seemingly care for him. * Tess: Completely unnecessary and out of place character. I think she's a huge con for the game, and the dangerous way in which she can affect the story. She deeply hates the demon lord, because she has been kidnapped too. Being from the isekai world herself, she has some basic magic skills. Anyway, she manage to drug the demoness somehow?, and let you have fun with her while she's asleep, by that shaming her(and you already have Tess's role elsewhere, in Emi and the head maid). That kinda ruin the immersion in the game for me for the mighty demoness which would kill you just for contradict her anyhow. And yet she's completely vulnerable without even suspecting it. I hope not, but i'm afraid that will lead to some bullshit blackmail at some point, at when you get strong enough to oppose the demoness, instead of developing some fun natural bond with her, or just let her rewards you for your service and loyalty, as she already does a couple of times by various ways. * Another weak point in the game for me is the text volume, especially during the h-scenes. Some of them are good enough, but others are literally under 10 sentences. As if they are there just for the overall count, instead of the meaning they should bring. I wish the game developer focus more on the quality over quantity as it should be.

It's got an alright story, good dialogue, alright looking models, but subpar sex animations. Definitely worth a quick playthrough if you've got nothing else to do. Story - 3/5 Character driven story with an emphasis on romance . Tone ranges from light-hearted to comical. The dialogue is fine, and the characters are distinct and memorable enough. The story is confined (mostly) to just the castle, making the experience rather homely. There is no world ending threat or grander plan, just you, the mentally unstable demon lord, and your harem. The game drops a few mysteries, and keeps you engaged with how it handles the demon lord. The character can and will kill you depending on your responses (making you roll back). She's absent enough to be a threat, and only shows up to move the plot forward as you try and guess what her aims are for the mc. By and far the highlight of the game Again, the story isn't great, but just good enough to warrant not being deleted from my system within the first 5 minutes of gameplay. Gameplay - 2/5 It's a fucking sandbox, but thankfully, doesn't have a grind (yet) as far as I could tell. You can grind a strength stat, but that does nothing so far. You just click between rooms to interact with characters, maybe make a few choices that show or skip a scene, and spam interactions with every room/character until you actually land on a story event. Very basic stuff, but inoffensive I suppose, as it could've been much worse. Koikatsu models tend to look absolutely horrendous, but this dev has made some mostly passable models, with the demon lord and the maid being some of the better designs. Fappability - 2/5 Sex scenes are pretty mid, and usually very choppy. Not a fan at all. Only thing saving it from a 1/5 is that there's at least some animation.

There is not much here at the moment, but what is here is very good. I like that there is actually somewhat of a mystery going on in the story so far, several actually. It make it interesting and different and i like the bread crumbs of information as to what is going on slowly hinting at a bigger story. The girls are all very nicely designed as well, however I do hope that they gain more personality as the story goes on and we learn more about them. Ultimately a great start and I look forward to revisiting when there is more here.
