I don't think so, but it would be interesting indeed.

I thought about it, but Oblivion already did it. So I need to come up with a new system to make wacky memes in my game 😆

The NPCs can now have conversations! Don't mind the text, it's a placeholder. #gamedev #indiegame #procgen

I will be speaking at GIC this year (gic.gd) with a talk called "The Possibilities And Limitations of Procedural Generation". It will be a fairly general talk about procedural generation where I will be using Vuntra City as a case study to make my points. Come check it out if you're there!

Game Industry Conference - 21-24 October 2026, Poznan.

Having an absolutely amazing time with Nivalis Nights, especially after installing a mod that slows down time. The original 60x time scale feels way too fast for a game where things happen on a schedule, and slowing it down to 15x actually allows for a chill exploration and life sim experience.

The NPCs will now evacuate if an uncontained fire gets past a certain size. For now I made them go to the other floors of the building and avoid the floor with the fire for 2 ingame hours. But if the fire is on the ground floor, they and other NPCs will avoid the whole building. #gamedev #procgen

Oh this one is a handful! I made them pretty rare, but they sure are fun to interact with (as long as you don't take what they say personally).

Oh and the NPC's reaction can depend on their personality.

A happy NPC saying "Yes... Haha, YES!" when another NPC got hurt.

I've added an NPC event system that lets the characters react to all kinds of situations. The standard events that only have dialog and/or animation reaction can be easily added via database without needing any code, but custom code for specific events can also be added. #indiegame #procgen

I'm so excited! Been looking forward to this one!

Vuntra City @vuntracity.bsky.social · 28/09/2026

I've added a way for the NPCs to say things outside of the player dialog. So they will be a lot more chatty now! There will be many situations in which they will voice their opinion, and their comments will depend on their personality. #gamedev #indiegame

New devlog on how I made 4 million NPCs playable in VR. Now, this performance is not ideal, it's more of a baseline, so the optimization work is not quite done. But it's a huge improvement from where I started. Check it out! www.youtube.com/watch?v=FkiA... #gamedev #indiegame #procgen

Then make sure to include Cerulean (I have a personal story with that color that is too long to tell here).

Vuntra City @vuntracity.bsky.social · 23/09/2026

Possibly many more, depending on how loose your definition of "not just associated with a combination of wave lengths" is.

Oh boy, this is my time to shine! Apart from the obvious metal colors (silver, copper, bronze, etc.) - nacre, peacock green/blue, neon <anything> (also "toxic green/yellow" or "hot pink"), champagne, titanium white, vanta black, denim blue.

Vuntra City @vuntracity.bsky.social · 22/09/2026

Ok I think I did it. 60+ FPS in VR on max settings, with 4 million total NPCs in the most crowded area of the city. Still not as stable as I'd like it to be, but it is quite playable so I'm happy! #gamedev #indiegame

Enjoying the last warm days of this year at the local park's jazz festival, and I can't help but feel that I need more cozy outdoor spaces like this in Vuntra City. I already have bean bags and string lights, but none of them spawn outside 🤔

The increased population certainly changes the city's feel in VR! #gamedev #indiegame #procgen

Everyone is playing around with DLSS5 and debating whether it's good or not, so here I have a totally legitimate comparison of Vuntra City with DLSS5 off and on. See for yourself!

Two screenshots side by side, one of a normal Vuntra City character and the other of a similar but more detailed character who bears uncanny resemblance to Lucia from GTA6, but totally isn't her.

You can't? Why did no one inform me? 😆

Vuntra City @vuntracity.bsky.social · 08/09/2026

Serious answer - I didn't consider picking talk to animals on my first playthrough because I didn't know how many animals were in the game beforehand. Definitely picked it for the second playthrough though 😁

Vuntra City @vuntracity.bsky.social · 04/09/2026

Awesome, I'll check it out when I get back to normal internet 😁

I tried to watch but unfortunately I'm at a place with shitty connection right now so all I got was a slide show. Will the recording be available later? Also the spider you is very cute!

I once googled an emoji (this one I think 🤷‍♀️) to find out its name, and the AI took it personally and got offended 😆

Just dropped a new devlog where I outline my struggles with increasing my city's population from 1 million to 4 million. It's kind of a work in progress devlog, but I hope it'll be interesting nonetheless. youtu.be/XsyYkEZF0rQ #gamedev #indiegame #procgen

Just heard about a cool pattern generator website bookofshapes.com. I wish they supported tiling patterns as well, then I'd totally use it to generate some new wallpapers for Vuntra City.

We recently got accused of using AI for music in our game and, while it's disheartening, it encouraged me to make a thread about making music for games, what it takes, and why it can be heartbreaking to be accused or even suspected of something we detest. 🧵Long thread follows:

I made the NPCs take their clothes off when relaxing at a spa and get into the hot tubs. Implemented an entire outfit system for it, so I can later use it to give them other temporary outfits. Also added steam to make the hot tubs actually look hot! #gamedev #indiegame #procgen

By the way, I am working on optimizing the game to run with >4m NPCs instead of ~1m that I started with. I'm still not sure I will succeed, as there are several performance bottlenecks that make it very hard, but the city sure looks so much livelier with quadruple the population! #gamedev #procgen

Vuntra City @vuntracity.bsky.social · 25/08/2026

I think games that involve stealth have that. When you have to plan carefully the order in which you take down or bypass enemies to avoid raising the alarm and then of course it all goes to shit and you just start blasting 😆

Vuntra City @vuntracity.bsky.social · 25/08/2026

Apparently, when there are too many NPCs in the same interior, they start playing a game of musical chairs of sorts. Watching them fight for a seat is pretty hilarious! #gamedev #procgen #indiegame

Also I've considered making the stars move as some other commenters suggested, but decided against it. I know it's unrealistic for the stars to be completely still, but because game time is faster than real world time, they'd be moving visibly all night and I find it a bit disorienting.
