🗓️ Planned Release

A lot of progress has been made since the last post and things are really starting to come together now.

Most of the core content for this update is in place, including new scenes, character interactions, and expanded mission content. I’ve also spent some time adding variation to certain paths so things feel less linear depending on how you approach it.

The story is beginning to open up more, and some of the underlying themes are starting to come through in a bigger way.

From a content perspective, the game has now grown to over 2,400 renders, with an additional 280+ renders in the promo/fan art folder, alongside 22 animations, so there’s a lot here in terms of both visual content and progression.

Right now I’m finishing off the remaining pieces and putting together one of the bigger sequences that will lead directly into the next chapter.

Not quite ready yet, but I'm getting close.

As always, I really appreciate the support.

Progress is continuing steadily, and things are really starting to take shape now.

Current Development Stats:

• 2,099 total renders in-game

• Word count holding steady (for now 👀)

• Animation count unchanged… but a brand-new animation is being finalised today once the render stitching is complete.

What’s New Behind the Scenes:

• Marcus’ repeatable route

• Followed by a… mystery option 👀

Story & World Expansion

• The sewer tunnel system is now built for Kate and Geoff to investigate.

  • Expect some tension…

  • A few laughs…

  • And one pair of high heels that absolutely were not designed for sewer traversal.

• The Masquerade Party outfit has been finalised.

  • Kate will travel and reveal herself in that look very soon.

  • And with luck… it hits exactly how it should.

The next phase of City of Sin – The Nocturne Files are well underway, and things are already moving faster than I expected.

So far, progress includes:

• 140 new renders completed (~1200 to 1800 expected)

• 7,429 new words written (and counting)

• A brand-new animation added

• Foundations laid for deeper, repeatable interactions and more player-driven moments

I’ll also be beginning work on the masquerade party very soon, and honestly I can’t wait to get Kate back into that outfit again for you all. That sequence has been living rent-free in my head for a while now.

This update continues to focus on expanding player agency, not just pushing the story forward, but giving you more room to shape Kate’s day-to-day decisions, relationships, and consequences. Including more detail on her background.

Below are a few early sneak previews from the new work 👀 (Still very much in progress, but I couldn’t resist sharing.)

As always, thank you for the support, feedback, and patience. Seeing how well the game has been received so far has been genuinely motivating, and it’s directly shaping how this next part is coming together.

More to share soon.

I am so happy and really rather proud of myself, I’ve just finished implementing a new optional interaction system in City of Sin – The Nocturne Files, and I wanted to briefly explain what it does and why it matters going forward.

This new functionality that will be introduced in the next update provides players with out of story interactions that exist alongside the main narrative rather than inside it.

What does that mean?

Certain encounters are now:

• Optional

• Player initiated

• Persistent

• And aware of past choices

Rather than being forced story beats, these moments arrive naturally via Kate’s phone and the player decides if, when, and how to engage with them.

You can:

• Respond immediately

• Put it off

• Decline entirely

• Or return later with the game remembering what you did the last time

No timers. No punishment. No “wrong” choice.

🔁 Repeat Visits, Escalation & Memory

If you choose to return to an encounter more than once, the game remembers:

• Who Kate previously chose

• How many times she’s gone back

• Whether she hesitated or committed

• And adjusts future interactions accordingly

Repeat visits don’t simply “loop” content, they escalate, both in tone and intensity and this lays the groundwork for:

• Returning encounters that deepen over time

• Familiarity changing power dynamics

• Tension building naturally rather than instantly

🌆 Why This Matters

City of Sin is about choice, consequence, and control, not just in investigations, but in Kate’s personal life.

This system allows players to:

• Shape Kate’s routine

• Decide how she seeks comfort, distraction, or risk

• Interpret her choices in their own way

• Engage with the city beyond the critical path

It also gives me a flexible framework to expand content without breaking pacing or story flow.

👀 What’s Next?

This same system will be used for:

• Additional repeatable characters

• Escalating side encounters

• Optional tension-driven interactions

• And future opportunities introduced earlier in the story

(Some of you will already have an idea of who and what that might involve.)

🖤 Final Note

Nothing in this system is mandatory. Nothing is rushed. And nothing exists purely for shock.

It’s about letting you decide how Kate navigates her life between the bigger moments and letting those decisions quietly shape what comes next.

As always, thank you for playing, testing, and pushing this game forward with your feedback.

Hi everyone,

Thanks to ongoing feedback and requests from the community, I’m happy to say that I’ve now resolved the translation and font issues, and the game has been updated with the following language support:

• Chinese

• French

• German

• Italian

• Russian

• Spanish

• Turkish

This update improves readability and font rendering across all supported languages, making the experience more accessible for a much wider audience.

Your messages, reviews, and discussions genuinely helped push this forward and more languages are already planned as development continues.

I’ll be updating the store page shortly to reflect the new language support.

As always, thank you for playing, for the feedback (good and bad), and for helping shape City of Sin - The Nocturne Files.

City of Sin – FAQ & Design Notes

❓ What kind of game is City of Sin? City of Sin is a narrative driven adult visual novel with psychological, investigative, and erotic themes. It blends choice driven intimacy with long form character development, trauma processing, and gradual world building. This is not a “scene-to-scene” adult slideshow. The erotic content is deliberate, contextual, and tied to character state and player choice. ❓ Who is Kate, and what is she doing? Kate is not an avatar and not a blank slate. She is:

• Former special operations.

• Trauma survivor with dissociative tendencies.

• Currently working covertly, under surveillance.

• Actively resisting both emotional attachment and self-destruction.

• Episode 1 is intentionally written to place the player inside her head, before fully explaining her history.

• Her backstory, motivations, and how she ended up working with Mitchell are expanded significantly in Episode 2.

• This is a slow-burn reveal, not a lore dump.

❓ Why is there so much narration? This is a deliberate writing choice, City of Sin leans toward psychological interiority the narration reflects:

• Kate’s dissociation.

• Her hyper awareness of surroundings.

• The way memory, sensation, and trauma bleed together.

• The narration is not there to describe what you can already see, it’s there to describe what the character is experiencing.

If you prefer:

• Minimal narration

• Faster pacing

• Visual only storytelling

This style may not be for you and that’s okay. But the narration density is intentional, consistent, and central to the story being told. ❓ Why does Kate spend time dressing, showering, walking, etc.?

• These moments serve three purposes:

• Grounding: Mundane actions contrast with violence, trauma, and erotic escalation.

• Character control: Kate reasserts control through routine and physical awareness.

• Player pacing: They create breathing room between intense scenes.

These moments will increasingly become interactive, rather than purely observational, as the systems expand in Episode 2. ❓ What is the phone system and what will it do? The phone is a core gameplay system, not just a UI element. Going forward, it will allow:

• Optional encounters (massage, gym sparring, photoshoots)

• Relationship follow-ups based on prior choices.

• Branch-specific content (straight / lesbian / dominance dynamics)

• Missed opportunities if ignored.

• Emergent events triggered by timing and availability.

This creates a controlled sandbox layer:

• Not fully open-world

• Not random

• But reactive to player behaviour

Think of it as a living schedule, not a quest list. ❓ Is this a sandbox game? Not in the traditional sense. City of Sin will use a “reactive narrative hub” structure:

• Story missions anchor each episode

• Optional interactions exist around them

• Choices affect availability, tone, and consequences

You won’t be able to do everything in one playthrough and that is intentional. ❓ Why do some erotic scenes end abruptly or shift tone? Because Kate’s agency matters.

• Sexual tension, arousal, and intimacy are often:

• Interrupted

• Redirected

• Complicated by trauma, surveillance, or mission priorities

This reflects Kate’s internal conflict, not a lack of content.

• Episode 2 expands erotic scenes significantly, especially around:

• The masquerade

• Power dynamics

• Consensual escalation

• Player-driven continuation instead of hard cuts

❓ Will Episode 2 explain more of the story? Yes ,explicitly. Episode 2 covers:

• Kate’s past in detail

• Her relationship with Mitchell

• The desert mission

• A wedding and its aftermath

• Why certain triggers affect her so strongly

• How her coping mechanisms formed

• Episode 1 sets the pressure. Episode 2 releases it.

❓ Is this connected to other DoAdventures stories? Yes. City of Sin exists in the same broader narrative universe as Jessica's Choices, but is designed to stand on its own. You don’t need prior knowledge, but long time players will notice echoes, parallels, and callbacks. ❓ Who is this game for? City of Sin is for players who enjoy:

• Character driven storytelling

• Erotic content with narrative weight

• Trauma aware writing

• Slow escalation

• Choice with consequences

If you’re looking for:

• Fast gratification

• Minimal reading

• Kink-only branching

This may not be your preferred experience and that’s okay. Final note from the developer City of Sin is written with intent. It is not trying to be everything to everyone. It is telling a specific story, in a specific voice, at a deliberate pace. Thank you to everyone engaging with it in good faith, your feedback genuinely shapes where the story goes next.

Episode 2 of City of Sin – The Nocturne Files is officially underway.

I’ve just pushed a hotfix update to address a small issue, and with that out of the way, development on Episode 2 has now properly begun.

Where Episode 1 focused on tone, character, and laying the foundations of Kate’s world, Episode 2 shifts gears.

What Episode 2 Is About

Episode 2 expands player agency and begins introducing repeatable encounters, systems that let players re-engage with characters and situations over time, rather than experiencing everything once and moving on.

At launch, this will likely begin with two repeatable encounters, but more importantly, it establishes the framework that allows these systems to grow and evolve across future episodes.

This means:

• More player-driven choices outside of linear story beats

• Optional encounters that can escalate over time

• A world that reacts to what you pursue and what you avoid

Why This Matters

City of Sin is designed as a slow-burn series, where each episode builds on the last rather than resetting the board. Episode 2 is where those longer-term systems start to take shape.

Some of the groundwork you saw in Episode 1 with the phone, character connections, and locations begins to pay off here.

Development Status

• Episode 2 is in active development

• Systems and structure are being prioritised first

• New scenes, encounters, and escalation will follow

I’ll be sharing progress updates and previews as things solidify but please see some early images from Episode 2 are already attached to this post.

Thank you to everyone who’s played, reviewed, wishlisted, and shared feedback so far, it genuinely helps shape where this goes next.
