Red Flags: Infidelity Island is an adult visual novel by Lostworks, built in Ren'Py with animated 3D CG artwork. You play John, a second-year college student whose summer vacation with Mia turns complicated when two other couples are on the island trip. The cast includes Hayley, a childhood friend, her boyfriend Steven, Emily, and Jake, all carrying old friendships, rivalries, and unresolved history. The story focuses on cheating, teasing, and voyeurism as tensions rise and John and Mia’s relationship is tested.
The current build is v0.7, released August 28, 2026, and development is ongoing. It runs on Windows, Linux, and Mac in English and is uncensored. The update centers on Hayley taking the main characters to a museum to avoid Steven’s mother, moving the group closer to the edge of infidelity. The notes also say later versions are planned, with v0.10 intended to conclude Chapter One.
Developer's description
It's the second year of college and John and Mia are going on that island getaway for summer vacation? The problem? There's two other couples on that island: Hayley & Steven and Emily & Jake. Hayley's been your friend since you were kids and Steven used to date Mia, Emily used to hate you and Jake's always been a fiend. With tensions and drama set to flare, is it possible for John and Mia's love story to emerge unscathed? Or will the red flags on infidelity island consume all?
v0.7
So, in V0.7 we have Hayley dragging our protagonists out to a museum because she does not want to put up with her beau Steven's mother. Unfortunately, this pushes our characters ever further onto the precipice of infidelity.
Now, V0.8 and V0.9 are already written. I am planning on writing V0.10 tonight but I will say, what happens in this update is wild and it ensures that things are going to cross over next update and all the way up until V0.10, which will end Chapter One.
What about Normal Trade Relations? I've completed all the animations that game will have and got to 130/250 renders like I wanted. I will be trying to get more renders in before the month is done and hopefully I can get to about 200.
v0.6
There are 470 renders and two custom made animations that I'm very proud of which are featured in this update. There's also new music being used in these scenes. We are definitely on the precipice of the infidelity part of the name coming true.
v0.5
N/A
v0.4
Now, what's new in V0.4? We have a huge update, possibly the biggest one that I've done yet. It takes our protagonists and puts them on a party ship and we really see the tension between all three couples flare to conclude Day 4 of the game. What I feel that I've done very well in this update is that I treated the entire thing like a sort of minigame. I run you through a bunch of options and then depending on how those options go, you get one out of four different ways to end the update. How this update ends will affect future releases. I don't know if I'll keep making them like this, V0.5 will be more linear, but I thought it was a very neat idea. i think it encourages you guys to go and look for the other content.
So overall, I made over 500 renders for this update and that number gets closer to a thousand when you factor in the three great animations for it.
v0.3
For those of y'all wondering what's covered in this update, we have the end of Day 3 and half of Day 4. The rest of Day 4 will be the focus of V0.4 whose screenplay I am currently writing right now. There are hundreds of renders in this update, two animations which I think that you all will love.
Overall, this update sets up an even bigger update and I'm glad that I was able to get both this and The Boston Breeder out in one month. As of now, it's only scheduled to be Infidelity Island next month but who knows how fast rendering will go. Either way, I'm sure you guys will love this update!
v0.2
I finished work on it last night and decided fuck letting it stew, we'll give it to y'all today. There's about 270-280 renders, closer to 600 when we count the three animations. So it's a huge update and it really starts to hone in on the type of stuff we're going to see on this island in coming updates.

Well, I tried this game despite red flags. And damn, the game is really just horrible. Renders are straight from 2017 with primitive shaders and lighting. Characters are absolutely ugly. Horrendous face sculpting, robotic poses, non-tight "flying" clothing, and ugly…

Wow. The models are, honestly, just hideous. I mean, they aren't even 'average' sorts of looking. This is like someone intentionally set out to make the most horrifying models they could for a game like this. I can't speak to…
