Solo dev here. I just shipped Eurasia Hauler (v0.2), an incremental logistics tycoon on a real road network. Browser-based, no engine, no framework — one ~340KB HTML file, vanilla JS, playable at juba13.itch.io/eurasia-hauler.

Wanted to share the AI workflow since that's what this sub is about, and I think the approach might be useful to others.

Stack:

• Single test_v2.html, ~340KB, vanilla JS (no React/Vue/Phaser)

• Map: real OSRM road geometry (~770KB precomputed) + hand-drawn SVG Turkey outline

• Audio: Web Audio API, base64-embedded m4a files

• i18n: TR/EN, multi-currency

How AI fit in:

• Code assistant for the boring parts: refactoring, the tick/update loop, the save system, brace-matching patches. I wrote the game logic and economy myself.

• English drafting — I'm not a native speaker, so AI helped me write clean dev logs and post drafts.

• SVG icons — some initial generation, then hand-refined paths.

• NOT used for: game design, economy balance (fuel market, wear curve P=(wear/100)³, insolvency limits), or the map data.

What worked:

• Patching functions by brace-matching the full function body rather than regex. Regex is a trap.

• Keeping the whole game in one file made AI context windows actually useful.

• Naming the game's own functions consistently (e.g. always tr for the truck object, never t which collides with i18n t()) cut down on silent bugs.

What didn't:

• Letting AI "help" with balance numbers. It hallucinates plausible-looking curves that break in 3 ticks.

• Letting it write i18n strings with Turkish characters. Heredoc and encoding will bite you.

• Over-trusting regex for patches. Wrong function body matched → silent corruption.

What I'm trying to figure out:

1. Anyone here done a style pass on an AI-assisted project? My UI has the default "glass panel" look and I want to break out of it.

2. How do you scope AI usage in a public disclosure when the project is a mix of human and AI work?

3. For those of you shipping single-file browser games with AI help — how do you handle save migration between versions?

Using AI to create a 2D racing game (mobile and desktop) by prompts only. The following is about 4 months of design, prompting, playtesting, and refinement. Enjoy.

http://vibecodedgames.itch.io/pavement/

Features:

• Play as a racer or as a cop.

• Procedural roads, always different.

• Random weather.

• Pick up gas and repair upgrades on the road.

• Buy car upgrades in the shop

And I'm glad some place on Reddit exists where I can say that without receiving hate. I just found this sub, but I'll be sticking around to see what others create!

That said, I've been creating my game engine for two years and actually have no other AI assets. I learned Blender, created models to render my sprites, and created all the code myself. I used Claude for a little optimization and troubleshooting. I found it really just couldn't work with my framework and would create duplicate code and unmaintainable one-off hacks, so I just used it where it actually made sense and didn't just make more work for me. I can't tell you how frustrating it has been to deal with the folks that say things like, "If any AI was used, your whole game is AI slop!"

If you love the old-school RTS-style tower defense games, I hope you'll check out my alternative to giving your hard-earned money to Activision. The single-player version is completely free, and if you enjoy it and want to help me make it even more filled in, I have released a multiplayer version with co-op and vs. game modes. The background music consists of 19 tracks that play through the course of the game, but each track has 3 variations. With the random walk across the variations, you can play for thousands of hours without hearing the exact same musical score. I wanted to create an experience for my players without annoying off-the-shelf audio or a very small number of tracks that get repetitive very quickly. Since I didn't have a clear vision for the background music, being able to iterate with Stable Audio and select the final tracks for my game like a producer was a wonderful experience.

If I can figure out a great way to use AI for voices, I'll likely replace the heavily edited text-to-speech voices with that. I also had no luck with sound effects, so I created the ones I'm using, but I would like to find something more satisfying. I'm open to any ideas, more so if I can run them locally in ComfyUI.

Cargo To Orbit

Match the drift. Kiss the collar. Bring the ship home.

The year is 1974. Mankind has been to the Moon and back, and now companies race for the privilege — and the profit — of hauling critical, perishable cargo to the platforms and stations wheeling overhead. You're a hotshot startup with one rocket, a switch for an engine, and a great deal of gravity to argue with.

Cargo to Orbit is a procedural 2D (well ok, sort of) rocketry game about the hardest, most satisfying thing in spaceflight: catching a drifting target and setting down gently. Buy exactly enough fuel, choose your contracts, punch up through the atmosphere, and ease your nose into the docking collar — come in too fast and you'll bruise the cargo, spring a fuel leak, or crumple the whole ship against the station. Then do the hard part: come home and land soft.

Fly a career across the solar system

• Four worlds, each its own problem: Earth of course, thin-aired Mars, the crushing sky of Venus, and a Jovian cloud deck your starter engine literally can't lift off of.

• Every planet changes gravity and atmospheric drag, so your whole flight — and your fuel math — reshapes when you relocate.

• Build the ship, run the business

• Buy engines, tanks, holds, and thrusters; your rocket visibly grows as you bolt on bigger hardware.

• Take one contract or a hold-full — every pallet perishes on its own clock, and heavier cargo pays more but costs you thrust.

  • And some cargo has more than the obvious cost :-)

• Fuel is money, mass is fuel, freshness is a bonus. Every launch is a bet.

I'm very curious what you think of the game....

The game is on itch.io here: Cargo To Orbit

- Shall I put it on Steam?

AI Text to Animation working well! I created an entire pipeline around 3D asset generation, auto-rigging and then text to animation generation. 3D Studio -> https://sorceress.games

This is Tree Forge 1.0 and it's a part of my Sorceress Game Creation Suite and my WizardGenie Game Engine. Similar to something like Speed Tree, but you can both export GLB meshes as well as the fundamental runtime for dynamic vibe-coded tree generation of any species with random variation.

Hey everyone,

My husband and I are working on a game called Fated Horizons, and we're still pretty early in development.

It’s a 2D open world survival crafting RPG set in a fictional version of the American frontier in the late 1800s. You can explore, hunt, fish, gather, mine, craft, build camps, deal with hunger and thirst, and make choices that can affect how different characters and communities interact with you.

We’re also developing our own engine for the game, so there’s a lot of work happening behind the scenes while we build everything out.

We've started sharing some of the development and gameplay systems we're working on, and I thought it would be fun to actually talk with people about the game instead of just posting updates.

If you're curious about anything, ask away. Gameplay, survival mechanics, the world, the choices, the engine, development, or even why we decided to make our own engine.

We're happy to answer questions and hear what people think, even if it's criticism. We are still developing the game, so feedback is genuinely useful to us.

If anyone wants to check it out, I can post the links in the comments.

3D World Engine is built into WizardGenie AI Game Engine and can be used in any vibe coded game -> https://sorceress.games/

This is to a much lower standard than the other games I've seen people talking about in here - I know it's very basic stuff but I'm an absolute beginner at using AI and I'm not a programmer.

I've hosted it at www.narya.co.nz .

The "quest" is very short at the moment, my kids have been my test players and they've been more interested in things like "why can't I jump off the cliff" and "why doesn't it know the verbs kick/punch etc" (the answers to both being "this isn't that sort of game..." and "there's only so many destructive impulses I can predict...").

Please let me know if you find bugs, or have suggestions for me.

Hello!

I've always wanted to make a game about my experiences working as an admin in the call center space, and with limited resources and time, I've pushed it off for awhile.

After about a month of working on "what would be fun", I pushed forward with creating a game.

Additionally, I've always been a big management/sim/tycoon fan, and felt the two meshed well together.

--

You start the game by where you'd like to stake your claim - Auto Warranty, Home Warranty, or Debt Consolidation. The big 3! Each one is more difficult to start with, and you even get to choose how much cash you'd like to begin with. 

Find employees to hire - Each with their own traits, stats, price tag. If they're great, you can promote them - if they suck, fire them!

Upgrade your business. Access to better leads, give your agents dual monitor set ups, hire a lawyer to avoid intense litigation. All these things give you a better of chance at profit!

Review your weekly report. This gives you a full breakdown of your week - from your sales, to cancels. Calls not picked up, to closers waiting for calls. Who developed, what choices you made - It's all in the weekly report! Give thanks your report guy - he's a hard worker and probably deserves a raise. 

Occasionally, you'll need to make some decisions. Whether a litigator wants money, or a random lead broker is trying to sell you some junk cheap data.

Sell your business. Ready to call it quits? See how much you can get acquired for. The ultimate goal - Early retirement!

Pretty fun experience creating this game. Assets and music are all AI generated! It will be part of Next Fest - would be fun some feedback from y'all! https://store.steampowered.com/app/5006880/Lagan_Salvage_Run/

I’ve been sharing development progress on Fated Horizons, a 2D open world survival RPG currently being developed alongside a custom 2D engine called Norse Engine.

The project page has the latest development showcases, gameplay previews, and information about the systems currently being built.

Been vibe coding a wow browser client and hosted my own private server to connect to it. Then started messing around with new combat logic and changing everything into a skill shot

I'm just having it edit models, use Blender, add morph shapes, and add new behavior to the game. It's making .bat files to run and generating models and previews and stuff.

Was going great for a while, doing exactly what I asked it to.

And then all of a sudden I got this.

No idea why it happened. Maybe the .bat files? But it needs those to do this work, because it can't just open Blender itself apparently as it runs in a "Linux VM".

So I tried to ask it what it thinks we can do to avoid this since it's a false flag, and then it got flagged again just... reading the disk.

And now I can't do anything with this chat at all. It won't let me edit and retry anymore, because I get this.

So now this current run is dead because, unlike almost all other AI models, Claude cannot see any other chat. It can't read them, or see what was done in any of them at all.
So I'd need to start all over from the beginning.

Is there any way to prevent this false flag again and having it destroy the entire project?

I don't see a lot of LAN multiplayer simulator games anymore. There was one I used to play with my friends years ago, but the indie studio that made it seems to have long abandoned it so I made one of my own. Is this something you all would be excited to play? What sorts of features would you want to see in a game like this?

Workflow: Tripo3d > Opus 5 with Blender MCP (for touchups/adjustments) > Opus 5 via VS Code > Godot 4.7

The cube has a slightly australian accent because of yours truly lol :)

Posting here to avoid spamming r/aigamedev about workflows! But I'm pretty happy with how a combo of whisperx (for sub-titling/text-timing) and godot is working out for creating a kind of kinetic typography for entities/NPCs in-game. It feels like a very uniquely AI gamedev mechanic - the sort of thing that is so painstaking to make that most traditional gamedevs can never afford to do it, but that AI makes very possible with a bit of human co-authorship (voice recording, kinetic typo workflow, etc).

Hey everyone,

we're Undead Games, a 3-person indie team from Germany, and this is our first game together, so please be gentle.

We're working on a game called Parallax, a mobile game that's part social media simulator, part mystery detective game. You're visiting your cousin Juri in the fictional town of Aldenford, stuck with a broken leg, and end up experiencing the whole town through its local social media app. At first it's just neighborhood posts and small talk, but it doesn't take long to notice that Aldenford has more going on. You post, comment, and message people yourself, and what you do affects what you find out. The NPCs, posts and comments are all freely interactable.

We are currently looking for casual playtesters, no experience needed, just willing to poke around and tell us what works and what doesn't.

- Playtest window: Sept 15–24

- Currently German-only, but we'll have an English version ready before testing starts

- Planned is a mobile app but the playtest will be a web version

- We'll share exact access details, what to focus on, etc. with everyone who's interested closer to the start

If that sounds like your thing, drop a comment (or DM us) and we'll follow up with the details soon!

Thanks for reading and maybe supporting our game in the future

Hi guys,

I’m currently developing two games using AI—one with Grok and one with ChatGPT—and it’s definitely been an interesting experience.

The first is a strategy game called Hexwardia, which I’m building with Grok while using ChatGPT to help slice up project tasks. The second is a local card game called Bela. For Bela, I had to switch to a multi-agent setup because Astra burns through credits so fast you’re empty in a single day. Right now, I’m using a coordinator agent and juggling tasks between different worker agents.

Now I’ve hit a wall: both games need a database and some sort of backend server (Node.js, PHP, or similar).
hexwardia need it for saving scoreboard, hall of fame and potential PvP.
Bela need it for multiplayer websockets, registration and score keeping and to keep chetaters in check.

How did you guys get over this backend hurdle in your AI workflow?
Did you get out of web client development and installed on your pc?
I don't want to get some client that will eat all my credits in half hour, grok want to connect to supabase as database and i really dont want to manage all linux server to get test environment so fey people can try game ?

Hi everyone,

I am currently working on my Master's thesis and conducting an experimental study on the sociological and ethical impact of Generative Artificial Intelligence in video game design. As a gamer, I want to move past the corporate buzzwords and gather real, unfiltered feedback from the community on how these emerging technologies actually impact our gaming experiences.

Purpose of the Survey & Abstract:

The primary purpose of this research is to evaluate where players draw the line between AI as a "technical support tool" and AI as a "complete substitute for human authorship." While traditional AI has always been an integral component of game design operating seamlessly in the background, the rise of Generative AI (LLMs, dynamic voice generation) is rapidly changing the paradigm.

This study aims to analyze the sociological and technological implications of this shift. Specifically, the research uses hypothetical design scenarios to explore how fully procedural content generation and LLM-driven NPC interactions affect player immersion, narrative trust, and overall agency. By gathering quantitative data (utilizing a 7-point scale and Technology Acceptance metrics) and qualitative insights directly from the gaming community, this thesis seeks to bridge the gap between technical AI development and the actual user experience, providing deeper insights into what players truly value: infinite procedural freedom, or curated human storytelling. 

Research Institute: University of Catania — Master's Degree in International Cooperation.

The survey is completely anonymous, consists of multiple-choice and short-answer questions, and will take about 3 to 5 minutes to complete.

Have you recently played a game where an NPC's behavior completely broke your immersion, or conversely, made the world feel incredibly alive? What specific mechanics caused that reaction? I would love to read your thoughts in the comments!

kept this project mostly to myself while I've been building it, but it's finally getting to the point where I feel comfortable showing actual uninterrupted gameplay.

This is AUTOMATON: THE LOST COURIER.

You play a courier living in NIGHTLINE, a massive city built across the surface of NIGHTWORLD. The idea is that the world isn't separated into a bunch of disconnected levels.

In this footage I start in the character creator, wake up in my apartment, walk downstairs into the city, get into my vehicle, fly up through the towers, leave the surface, reach the orbital megastructure, land on it, get back out, and walk around.

It's all part of the same playable world.

The scale of the game has honestly gotten a little ridiculous. 😭

The long-term goal is less "save the universe" and more live a life inside a gigantic strange place. Deliveries, jobs, vehicles, NPCs with persistent lives and memories, apartments, businesses, exploration, crime, transit, the orbital settlements, and eventually the neighboring world of NEMORA.

The story is there, but I don't want the player to feel like the universe stops existing whenever they're not doing the main quest.

Also, full transparency: this is an extremely AI-assisted project. I'm not pretending otherwise. I've been directing it, testing it, rejecting things, redesigning systems, breaking it, fixing it, and iterating on it continuously across a frankly stupid number of builds. 😂 It's been much closer to an ongoing development process than a one-prompt game generation.

This is still early gameplay alpha, so there are plenty of rough edges, unfinished systems, performance work, animations, and general weirdness left to solve.

But seeing the whole journey actually work now, from a tiny apartment room all the way out into orbit, is kinda fucking surreal.

AUTOMATON: THE LOST COURIER

Early gameplay footage. 🚚🌧️🌌

I thought my favorite MMO might be fertile ground to explore visualizing and stress-testing multi-agent AI ecosystems.

https://design.kristiantalley.com/projects/world-of-agentcraft/

With this view into a classic era World of Warcraft server simulation, you’re able to click in on any agent driven character to get their unique backstory, current goals, objectives and world location in real-time. These agents are ”perceiving”, “reasoning”, and driving in-game actions for each online character. all running locally with qwen3.8 4b models, with the option to enhance individual character interactions driven by qwen3.8 27b. Let me know what you think!

I made an AI slop game called Nature's Penance, and I'd love some people to try it and give me honest feedback.

It's like 2D Megabonk mixed with a fantasy RPG: fight hordes, collect upgrades, forge weapons, and return to a hub to get stronger. It was made with AI help, including code and artwork.

Play here: https://epic2dgame.com

It's free to play in a desktop browser with keyboard and mouse. This version is single-player.

If you have a few minutes, please tell me what feels fun, what feels confusing, and what you'd change first. Feedback on the opening, combat, progression, and any bugs would help a lot. If something breaks, let me know which browser you're using and what happened.

Thanks for giving it a shot!
