Overview:
Luminary Protocol is an adult Isekai visual novel with a dark, unfolding narrative. You, along with others, are torn from your reality and thrown into Lumis—a dangerous, magic-filled copy of Earth ruled by enigmatic gods and demons.
The story begins with familiar genre tropes but quickly descends into a desperate, life-or-death struggle. Expect a mature story featuring graphic violence, sex, nudity, adult themes, and substance use.
This is my first game, I have no development experience at all. I picked up renpy back In January and this is the result of many trial and errors.
Explore a Shifting World
The world of Lumis is unstable. Chunks of other worlds are regularly transported there, merging with the landscape. This phenomenon, known as a 'Convergence,' brings new creatures, peoples, and technologies, offering unique locations to explore beyond the core world.
Your Path Through the Story
The game follows a linear main story, but your choices matter.
Flavour Choices: Most decisions will change your immediate experience and perspective on events, rather than branching the main plot.
Key Events: Rare, pivotal choices will have a significant and lasting impact on the story's outcome.
Alignment System: Your actions will align you with Order, Chaos, or Balance. I consider the 'Balance' route to be the canon path through the narrative.
A Note on Development & AI
This project would not exist without the use of AI tools for asset creation, as I don't have the budget to hire artists. This allows me, as an amateur solo developer with no experience making software, to pair my writing with the visuals needed to bring the world of Lumis to life.
The Road Ahead: I’m releasing the game at this point because I have finished building the technical framework that the mission system uses and it has a pretty good amount of content for a first release. Now I can just get on with new content, rather than worrying about trying to work out building UI, menu and mechanics. My goal is to release a new chapter/update every 1-2 months (ideally 1, but I've seen too many games over-promise and under-deliver with timescales). I intend to release updates as at least one fully complete “adventure” for one of the factions in the game, similar in size to what happens in Chapter 2. Alongside that, I hope to include some smaller scenes, where you get to spend down time or go on other adventures with specific characters. That’s the idea.. at this stage I’m still working out what is feasible as a part-time developer.

Extract and run
- v0.22
- Corrected some spelling errors.
- Corrected some images not displaying in the galleries.
- v0.21
- Re-worked the gallery as I didn't realise that the first time you went into the gallery, it fixed all the images forever. Should now dynamically update as you progress.
- Fixed a video not playing in one of the camp scenes.
- It turns out it was 6 new animations for Isabella, I had added two versions of the same scene and set it to the wrong version. Now plays the right video.
- Fixed a few spelling and name issues.
- v0.20
- Enhanced the sex scene in chapter 1 with several animations.
- Added a linking section to explain what happened in the 2 month prior to the MC's graduation.
- Added the first mission for the Cartographers Guild.
- Overhauled the character galleries, allowing a greater variety of images to be shown and therefore a greater number. Added a system to patch old saves to make sure all the images are visible that should be. Bear in mind that these galleries will display the entire sprite and they weren't always intended to be shown in their entirety. So some may have mangled hands/feet etc.
- Spent some time working on the mission management system to better enhance it.
- Added systems to track maximum potential scores for each stat in the game.
- Added a general key information update popup (quest outcome, key decisions etc.)
- Fixed issues where the MC's default name was still in the script instead of the player chosen name.
- Added a system to customise relationships between key characters (needs a new save - sorry).
- Updated the display text to be on a completely transparent background. To keep it visible the font is now displayed as white with a black outline. All narration and spoken text uses the same font, the side images should be enough to indicate when it is speech over narration.
- Enhanced some of the original Chapter 2 content with a couple of additional animations.
- Some 0.2 stats:
- The story of the adventure is around 18-19000 words. There are several variations of key events so the amount each player will see on a single playthrough I would guess at being about 12-14,000.
- The update includes more than 3500 lines of scripting in renpy.
- 28 standard backgrounds and 8 animated backgrounds.
- 72 sprites and 25 animations of Emelia.
- 3 equipment item sprites and 3 illustrative images.
- 11 sprites of the MC. 1 animation focused on the MC.
- 1 sprite and 1 animation of Alice.
- 1 sprite and 1 animation of Ethan.
- 6 animations for Isabella.
- 1 sprite and 1 animation of Lilly.
- 1 sprite and 4 animations of Sarah.
- 1 animation not already accounted for above added to chapter 2's farmhouse scene.
- 23 sprites and 11 animations for new secondary characters or encounters.
- v0.1
- Includes complete Prologue, Chapter 1 & Chapter 2
- Setup of faction and character plot and mission management systems.
This is my first attempt at a game. I hope it lands well, it’s not intended as a “quick release” kind of game. There is adult stuff in the first release, but the focus is the characters and the story. So if you are hoping for a shit ton of sex, this isn’t going to be the game for you. It will feature a lot of adult content, including a lot of nudity, horror, violence, drug and substance abuse, people doing pretty horrible things to each other, along with supernatural and magical stuff that definitely comes with an 18 rating.
Future tags (already planned for future releases):
BLACKMAIL, CORRUPTION, CREAMPIE, DRUGS, EXHIBITIONISM, FEMALE DOMINATION, FUTA/TRANS, HAREM, INTERRACIAL, LACTATION, MASTURBATION, PROSTITUTION, PREGNANCY, SEXUAL HARASSMENT, SLAVE, TEASING, BDSM
Future tags (possible, still considering if they will fit here or could be added but haven’t planned where or how yet):
CHEATING, MALE DOMINATION, GAY, HUMILIATION, LESBIAN, MULTIPLE PENETRATION, SEX TOYS, SWINGING, TENTACLES, TRANSFORMATION, SISSIFICATION, URINATION, VOYERUISM, ANAL SEX
Some (but not all, I don't currently plan to, but if I were to put gay scenes in for example) will be skippable. That or the storyline/character they relate to will sign-post it well in advance of it happening, so you can decide not to pursue that character/storyline. I get lost in what is considered NTR or not. There will be scenes where romantic interests end up in sexual situations with other characters or beings. It won’t be the player character or their partner getting off on it and it will be rare. It will be something that happens because their partner is a prostitute, a slave or captive, it is their job to do it to get something they need or result they need on a mission or it’s the outcome you choose to a major storyline point. This is a bad world, bad things happen and you won’t always be able to stop that.
