Unity - Midnight Sin [v0.8.1] [Faerin]

An excellent game by every metric.

The paths respective to each girl are a genuine joy to explore, as each character’s personality shines in their limelight; and the dichotomy of contrasting personalities leaves a savory taste in your mouth — like glimmering twilight and brightness of daylight. An obvious highlight, but an execution of this degree is surefire a competitive edge in its genre.

Even though there is more than a plethora of characters to be had, the game—at this stage—inevitably leaves you yearning for more. Like the perpetual stew, this game needs more content, more time to develop, and more to simmer in its own creative juices.

To those still tentative: technically, you could play it now and get a decent nut in, but you could also wait for a more complete experience. I promise you the holiest of nuts. The nut to end all nuts. Patience is a virtue.

I'm honestly a little shocked you can still be successfull with such a formulaic and predictable game in 2025.
This is a game you've seen a dozen times before only ..... worse somehow. Instead of perfecting and modernizing the formula of this "corrupt your family/sandbox/management" sort of game, or whatever you want to call it, it has all the problems that should be a thing of the past.

Bad Pacing, generic characters, boring plot, obnoxious "features" to waste your time, forced and unnatural progression of the relationships etc.

And ironically, many sandbox type games promise freedom, but in reality are among the most linear and railroaded experiences in the adult game business. This game is no exception. You have no freedom, you are forced to follow a specific path with zero possibilities to influence anything, including forced LIs.
Interesting characters or engaging writing could salvage some of the above, but you can find very little of that here. The MC's countless monologues are especially annoying. The whole incest thing is also done poorly. To be fair though, that's true for almost every incest game. Very few game take their time to make these relationships taboo and exciting, instead thinking a "oh my god, this is my sister" from time to time is enough.

So yeah, that was really disappointing.

I have played version 0.6.3 and It's another great game from Faerin. It's a sandbox, like his previous games, and a well executed sandbox at that.

Great models, interesting characters and fun.

Knowing that this game will be completed, monthly updated and not abandoned nor dragged out is a huge plus.

Highly impressed with v0.6.3. Played through all the available content in about a week and very excited to see what comes next! Great work.

I've played a decent amount of sandbox games, and while I feel like I got to the end faster than I expected to, it took a decent amount of time to warm the characters up to the MC - which makes a big difference imo when it comes to these types of games. I don't want to start a game and get to smashing immediately. I do like buildup, and the characters have a great level of it to make it work.

It's rare that I beat these games, but the fact that I'm at the end of this one says everything to me. Keep up the great work & in the meantime, I'm definitely getting into more Faerin Games.

Excellent game in everyway.

There is a story, events and achievements. That's a very good start to begin with. There are individual paths for each girl. Mystery of blackmailer and so on makes the game enjoyable. Finally, models and places are detailed beautifully.

It's true that I find this one a bit below the others, but to be fair, the previous two set the bar so high that this one still has nothing to be ashamed of compared to what's out there right now. I found it rather short, even though I played it before it was fully complete (13 hours, and I often clicked through without using hints, so it could be even faster).


The characters are less engaging and developed, in my opinion, because in the previous games, their roles and uses added a deeper psychological dimension. Here, it's more simplistic, but it doesn’t take away the desire we feel for all of them. The adult scenes are decent — we've seen better from the game’s creators, but they get the job done. That’s the thing: it gets the job done — it's a game that does the minimum.


The manor was so interesting with its management aspect that the wait for this one raised expectations. Still, it has a lot of good points. The sandbox is fine — some empty areas and a bit of hide-and-seek for no real reason, but overall it's well done. The progression of scenes makes sense… unlike in other games where the sandbox is either fake choice or has too many choices, which can mess up scenes and the girls' reactions. Here, the triggers are well handled. There's clear software mastery.


The story is intriguing, decent, a bit predictable, but the scenes don't come out of nowhere. Another strong point is the MC — thankfully, he's not too dumb and has reasonable thoughts and reactions. He's not unpleasant. You do need to be okay with a very muscular type, which can make it harder to identify with him, but that’s subjective.


All in all, it’s enjoyable — a good game whose older brothers already proved themselves. And if you compare it to what’s being made nowadays, it’s actually pretty solid.

Can't wait to see who murdered his father and what the maids have to do with everything. Would like a little more free use once you get their events done. But a very minor complaint. Hopefully, the dev will update soon, and I will be looking forward to it.

its a Great Game. Animation is good. Models are Fantastic and Unique. I glad you are able to skip days if needed as it cut down on unnecessary time. I'm love all their personalities and how they are all different

This is the best Unity UI of any AVN I've tried.

The UI does a very good job of feature parity with Renpy.

The models and renders in the game are excellent. Even the overweight one can still hold your attention

The writing is at the better end of the spectrum. The inner monologue and weak reasoning of the MC is annoying but the advancing the plot is done well and the english quality is consistently good

A very good game. Faerin has always struck me as being a very, very good dev without ever blowing my mind. But three games in and their consistency and craft is really beginning to shine. To me this is the best game they have made and I am super excited to see where it goes.

The girls all look great. Focusing on a small cast does Faerin well (I feel like Mystwood got a touch bloated) and all the girls feel distinct. There is a minor quirk where for some reason their forehead wrinkles are really prominent. Its not really a bad thing since it helps them to be expressive, but it is a touch odd. Otherwise its four hot gingers with different body shapes and ages. None of them are unlikeable and they all have a fun dynamic with the mc. Good stuff.

The MC himself is pretty cool. Never written too dumb, doesn't do things that are unnatrual. His model is pretty unique and distinct too.

The gamefeel and pace of the game is its strongest point. Never feels grindy and yet also doesn't feel like a slideshow gated behind excessive clicking. The sandbox feels purposeful, flavourful and breaks up the content perfectly. Improves on Man of the House in every way, and that was a fairly high standard.

In terms of the sex it is very...interesting. Faerin always struck me as a little bit too vanilla for his own good. Man of the House had one of the best put together Mdom corruption routes in any game. Perfectly paced, fun dynamic, great push and pull. But the sex was...dull. This game is too early on to make a true call on yet. But so far the sex is way spicier than his other games and that is exciting. There is a scene with the MILF towards the end of the current content that is super hot and if that is a vision of things to come I am excited beyond compare.

As long as Faerin doesn't get sidetracked adding in a bunch of new sidegirls and focuses on developing the four we have to their full potential, this may become a top 3 game on this whole site.

Great stuff.

Yo this feels like a full fledged game , sweet ui , nice models , awesome animations . And interestingly enough story started good but became shit.

but hey who is here for the story?

Anyways lovely work dev keep it up

Game version: 0.6.0

I've played the previous games from Faerin and somehow liked them. They did have a lot of grind, but the grind was integrated into a management sim, which made it much more enjoyable.
The stories at their cores weren't special, just good enough to knit the different characters together and explain the ultimate goal of the MC.

Midnight Sin picks up the same formula again, but with muss less effort, as it seems.
The story is okay, but the progression is so slow now, it's annoying. Sometime into the game you will have to start skipping days to trigger a certain event in order to progress with certain characters.
But unlike the predecessor with its hotel management system, where you could still have fun aside from story progression, Midnight Sin leaves you with a stupidly implemented travel map system, which will not tell you what events you might trigger at the different locations. I found myself traveling from location to location, trying to progress with any side stories, that weren't pointed out at all.
The NPCs are also boring and very generic.

All in all, it feels like a downgrade from the previous games, especially in terms of game mechanics/ side objectives.

Like other reviewers already mention this game is the weakest of the developers games and a major part isn't that this game is still in development.

It has weird pacing, with nothing happening for a long time in the beginning and then one sex scene after another. Another major weakness is the useless sandbox, it doesn't further the game and seems like a leftover from an earlier idea of the game.
Other reviewers also mention good dialogue and story, and I simply don't see it. There is barely any interaction with the characters for any of it to really show. It also is one of the major reasons why the game feels empty.
In conclusion I can't recommend the game, it feels empty and has weird pacing, the animations also feel dated.

Faerin’s games after Man of The House have gained attention in the adult gaming scene, but they have increasingly felt more shallow and less satisfying. Man of The House was a more successful title, offering better interaction opportunities and a greater sense of freedom for the player. However, the games that followed failed to capture the same depth.


While Faerin’s newer games still have a storyline, it often feels superficial and underdeveloped. The dialogues are short and lack impact, character interactions are limited, and they tend to become repetitive. Since the player's choices don’t have a significant impact, the progression feels mostly predetermined. Instead of allowing relationships to develop naturally, they follow a linear and predictable path.


Another major issue is that Faerin keeps trying to create a sandbox-like experience but ends up making something closer to a Visual Novel (VN). While the games appear to offer exploration and freedom, in reality, they are quite restricted and guided. The relationships with different characters tend to follow very similar structures, and despite the illusion of choice, the games ultimately provide a limited experience that often feels like playing a demo rather than a full-fledged adult game.


The success of an adult game is not just about presenting explicit scenes; it’s about making those scenes feel organic and engaging within a meaningful context. Man of The House did a relatively better job in this aspect, but in later games, the interaction mechanics became weaker, and the gameplay turned into a "follow the right sequence to unlock content" type of system.

Story (5/5) – A Refreshing Twist on the Genre
Forget the typical "loser-to-lover" tropes—this game flips the script entirely. You play as a hardened ex-bodyguard assigned to protect your late father’s widow and your three previously unknown step-sisters. The twist? These sheltered, emotionally starved sisters develop intense feelings for you, the one person trying to keep things strictly familial.

What makes the narrative compelling is the role reversal: instead of the protagonist corrupting others, he becomes the target of their relentless advances. The MC staunchly rejects their inappropriate behavior (yes, he actually has morals), creating a fascinating dynamic where the "corruption" flows in the opposite direction. But how long can he hold out? The tension is masterfully built, making this one of the most unique AVN plots out there.

Gameplay (3/5) – Functional but Basic
The mechanics follow a standard free-roaming, point-and-click structure where you explore environments and trigger events. While serviceable, it doesn’t innovate much—you’ll mostly be hunting for interactions rather than engaging in deep gameplay systems. A solid foundation, but nothing groundbreaking.

Visuals (5/5) – Jaw-Dropping Quality
Where this game truly shines is in its presentation. The renders and animations are nothing short of spectacular, pushing boundaries in a way few AVNs do. Even compared to major titles in the genre, this one stands head and shoulders above the rest. Lighting, expressions, and fluidity are all top-tier—enough to justify playing for the visuals alone.

Technical Execution (5/5) – A Rare Unity Success
Most AVNs rely on Ren'Py, but this developer has harnessed Unity’s potential to deliver smoother performance and enhanced visuals. The result? A seamless experience that avoids the usual pitfalls of visual novel engines.

Final Thoughts

• Plot: 5/5 (A bold, well-executed inversion of typical AVN tropes)
• Gameplay: 3/5 (Standard exploration, nothing revolutionary)
• Visuals: 5/5 (Pushes the limits of what’s possible in the genre)
• Tech: 5/5 (Unity used to its full advantage)

Verdict: A must-try for anyone tired of predictable adult VNs. The story’s unique angle and breathtaking visuals make it stand out, even if the gameplay doesn’t innovate. Keep an eye on this one—it’s setting a new bar

It's very good, good graphics and story, it needs a little more development of each character, making the puzzles a little easier, the game has good audio, and improving the event gallery

maybe adding 1 or 2 more characters

Review of [v0.5.3]

GOOD GAME
You arrive at a house to protect the girls and little by little you try to fuck each one...

The story is interesting and the landlady little by little becomes corrupted and you discover things about her. At first she is very hard on you and very professional but little by little she changes. Just like the girls you have to protect.
Each one has their own opinion about you, and you can see how you progress with them.

The conversations with them, the famous circle at the beginning is interesting but once you have spoken with each one it simply repeats itself over and over again.

PROS

• Very good quality renders
• Animations are hot and fine with audio
• The landlady it's te best part
• The details of the house are impressive.
• The system to see the progress is very good

CONS

• Sexual animations only have 1 animation in a single position
• Sometimes it becomes unnerving to wander around the house without knowing what to do.

RATING :

Content: ⭐⭐⭐⭐
Sound: ⭐⭐⭐⭐
Renders: ⭐⭐⭐⭐
Characters: ⭐⭐⭐⭐
Animations: ⭐⭐⭐⭐

Final conclusion: ⭐⭐⭐⭐ GOOD GAME with click&point touch
RECOMMENDED TO PLAY

Plot
★ ★ ★ ★ ★
This isn't the common loser MC tale that by miraculous ways ended up conquering tons of girls. He has a badass background as a highly trained bodyguard and ends up being the bodyguard of his own father's widow and finds out that he has 3 step-sisters that have never met before. The first thing he tries to do is gain his stepmother's trust by protecting and helping his step-sisters at all costs, but as they are lonely because of their lifestyle in confinement in a mansion and having an overprotective and strict mother, they end up developing a big crush on the MC. Here things get weird, he fiercely rejects them and the game becomes a kind of inverted corruption, they try to corrupt the MC instead of the opposite like in all other AVNs. The MC is clearly against incest and loves his sisters as a brother should love... But not forever!

Gameplay
★ ★ ★
It's a free-roaming point-and-click event hunter.

Renders and Animations
★ ★ ★ ★ ★ ★ ★ ★ ★ ★
This is the AVN's extremely strong point, and I can say with certainty that it's ahead of its time. I've never seen anything like it and I've played the main AVN's available on this forum. The renders and animations alone can easily give five starts for the game

Engine
★ ★ ★ ★ ★
The developer managed to beat Ren'py using the Unity engine.

I am aware that this is a game in development, but even viewed through that lens, it can't be rated higher than 3/5. And that's a real shame, since I really like Faerin as a developer.

Pros:
-Nice animations and images.
-An interesting story.
-Cool characters.

cons:
-Not all characters are developed. That might be due to being in development, and could change later.
-Lack of gameplay: For a long time, gameplay is limited to clicking 'next hour', untill a specific event occurs in a specific room. While we are waiting for that to happen, there is nothing to do. No interesting, repeating events. No change in the images of the girls. Nothing to do but click 'next'.
-Connected to that: A real slow development. The game gets steamy after a while, but it takes a long time to get there.
-Boring gameplay: Some of the gameplay that exists is 'hunt the pixel', where you have to find a specific item to click.

I will continue to follow this game, hoping for the cons to get fixed. It's not a total write-off, and has the potentiel for greatness. I really hope it gets there with time.

Nice models and good renders, also the main riddle was kinda fun and well thought through, played it with walktrhough however. Except for that riddle maybe, the ingame walkthrough works quite well in general and all-in-all the GUI is very user friendly for a sandbox game, so it doesn't feel too grindy.

That being said, the game is rather vanilla and boring which is why it gets only 3/5 stars. The girls have different personalities but the sex scenes are more or less completely interchangeable as it is so often the case nowadays with all these softwashed games. The whole BDSM/discipline theme makes kind of no sense because apparently they all just love it, so there is zero edge or spice or any hint for corruption. What's the point of all that hidden punishment room when they love it and are basically begging for it anyway? I don't mind the girls loving it "deep down" or them getting "accustomed" to the bdsm theme but since all the devs are shitting themselves nowadays when showing even the slightliest non-con or forceplay scene, the result is another run-of-the-mill boring vanilla sex game.
