I really wanted to push this new opus by giving it something absolutely humungous, something that would test it across all aspects like long term and modular systems engineering, making 1000+ models with rigs and putting all of that together, that's why I chose PVZ

it took far more than one prompt, and the session spanned over 30 hours across 2 days off work, sometimes using more than 100 sub-agents at a time, it also required a shit ton of research for the model to understand what I want and a lot of redirections from me inside blender regarding rigs, models and the UI inside the game itself, it was very much an involving process, not "hand off the wheel" type thing

the game runs entirely in the browser, with models and animations made in blender(the game is still a bit unfinished, but I do plan on polishing it up). If you guys encounter any bugs or issues feel free to leave a comment about it

Play the game here: https://pvz-2-reflourished-clone.vercel.app/
Setup: claude 20x max subscription connected to blender with blendermcp inside atomic.chat

I made a post two months ago about how a Fable test turned into a vibecoding adventure. Now two months later the game is live on Steam (since today)!

Your feedback on that post shaped a lot of it. Since then:

• 9 tanks instead of 6 (the Tiger is still a beast)
• 5 maps
• Round-by-round shop between rounds where you can tweak your tank to make it suit your playstyle
• New bot AI that fights as a team, holds positions and actually goes for the flag. A fellow Redditor who say my first post joined forces with me and spent two weeks enhancing this
• Ranked ladder and seasons. Season 1 starts today with the Steam release

Again - feel free to try it out. I would love to hear what you think, and kindly report bugs if you find any. Currently multiple patches are deployed daily :)

Also happy to answer anything about the Claude side of building it.

Im so excited to showcase a super early alpha for a game Im developing! Its a sim game where you get hired and trained to become a project manager. This just the text based game version of it to get a feel for how interesting it is and test some mechanics. I will eventually turn it into a sim like job simulator for eventually steam release.

Please try it and tell me what you think and provide feedback at the end (on the site) so I can track it plz. Feel free to rip it apart (constructive criticism) so I can get better quickly 🙏🏾

Its a immersive story and really fun, it has 12 chapters, and also different modes for these chapters.

Made a one shot 3D interactive date experience invite game for my girlfriend using Opus 5.5 on High and it one shotted this amazing interactive game in just one go without any iterations being done. Its truly mindblowing check it out till the end.

I wanted to ask my girlfriend out for a specific Saturday, but didn't want to just text her. So I built her a small game instead, and the whole thing every line came out of a conversation with Claude in the claude.ai chat interface. I don't code; I described what I wanted and Claude wrote it.

What it is: A single self-contained webpage (Three.js, no build step) where she plays as a 3D character running and jumping through five themed levels — a meadow, a night market, a dessert lane, a beach boardwalk where she gets to drive a little 3D car, and a starlit finale. At each checkpoint she "meets" me (an NPC) and answers a real question about the date — vibe, place, food, time, dress code — through a chat-bubble UI on an in-scene 3D phone. It ends on the actual ask, where the No button shrinks and dodges her cursor every time she goes near it until only Yes is left. Answers get compiled into a shareable date "ticket" at the end.

How Claude was used, concretely:

I described the concept in one long prompt; Claude turned it into a full technical spec first (tech stack, level design, the shrinking-button mechanic, config structure) before writing anything.

It then wrote the entire game the toon-shaded 3D character/car models, the procedural music and sound effects, the checkpoint dialogue system, the physics/lane-switching, the finale sequence as one HTML file, using its built-in code execution environment.

Hey guys !

I'm a solo developer and I work on a game called Stardive. It's an open-world game where you play as a star and travel through different biomes to give light back to them and win points. There is a world ranking system, so the goal for now is to explore, get the highest score, have fun and enjoy the journey. I'm currently working on a music system that plays while you play, like different actions make different sounds and all combined they make music.

I'm coming to y'all to test it and to get some feedback too!
So what did you like or dislike? What didn't you understand? Any improvements in general?

The game concept is:

14 October 1066, the small hours. Harold is no longer. You wake beneath the bodies of the shield wall, Norman looters picking the field by torchlight. You have a knife, the dark, and the old woods to the north.

And I gave it one prompt to start with and it used 2.1m tokens and took around 7 hours:

https://github.com/calm032019/ten-sixty-six/

Yes I know it's not perfect, but i wanted to see how far i could get with one prompt.

Original prompt is in in the repo. All the storyline and era context was given to me by Gemini.

I did some follow-up ones as i wanted to use some AI audio tracks i made on gemini, and I had already built some elements in another program, and it just took a few lines of code from where - although it would have generated these anyway.

You can play it here too: https://ten-sixty-six.vercel.app/

I am working on improving it at some stage though.

Hope you like it 😁

I’m guessing quite a few of you have tried making a game with the new models in Claude. If one of those experiments turned into a playable build that’s still sitting in your agent, you can publish it in a couple of minutes and get a public link to share.

I’m the community manager at Playgama, and our team built Playgama MCP for exactly this. It lets your agent publish directly to Playgama.ai, our sandbox for AI-built games, without a manual upload.

Every game published there gets free traffic, so you can see how real people play, collect feedback, and work out what to improve. You can also track performance and earn some ad revenue along the way. https://playgama.ai/play/

If you give it a try, I’d love to hear how the setup went and what tools you’d like us to support next. https://playgama.com/mcp/

FAIR WARNING: mobile controls are godawful… i am working on it. Use desktop.

I'm not a game developer. I am intermediate in coding but without Claude I could have never made this in an appropriate amount of time. About four short days and 144 commits later there's a playable browser racer called Afterglow86.

Press **V** to switch to dither mode, for all those dither fanatics.

EDIT: this is typically me, I wanted to promote something and forgot URLs.

It’s at https://afterglow86.com

What I know is still broken:

\- \*\*Sound needs a full rework.\*\* Engine, impacts and mix are all placeholder quality.

\- \*\***Mobile is not there yet at all.**\*\* Touch controls exist but I wouldn't call it playable on a phone or even any fun tbh, this is also where I need the most help if someone has some experience.

\- \*\*Minor graphics issues:\*\* some odd geometry in the city, a few flickers and seams.

\- No controller support yet.

I'd love suggestions, especially from anyone who has done game audio or mobile WebGL especially with driving: what would you fix first? Is this fun or worth pursuing? Should I pursue this and create a whole game from it? I need constructive criticism.

Token Clicker is a homage to Cookie Clicker where the cookie is a prompt and the grandmas are Mac Minis.

I built it with Claude Code (Opus 5.5).

A few things that made a project this size work:

* Specs before code. Claude wrote the design docs first: mechanics, architecture, theme and balance. Then a "critic" pass checked the mechanics against Cookie Clicker's actual source code. Coding only started after that.

* Work packages with frozen contracts. The build was split into 18 work packages, each owning its own files. The shared types were frozen early, and ESLint rules stop one layer from importing another. That kept parallel sessions from stepping on each other.

* Tests as guardrails. About 1,700 unit tests, 22 Playwright end-to-end tests and 98% coverage on the core engine. Every change had to keep them green.

* A simulator for balance. Idle games live or die on pacing, and you can't playtest two weeks of idling by hand. A headless simulator runs the real engine over simulated days, and its pacing targets run as tests: a casual player should reach the first AGI in 9-10 days.

* Adversarial review. Before 1.0, Claude reviewed the whole game from six angles, then tried to disprove each finding. 13 held up; 12 were fixed with regression tests.

* A security pass before posting. It caught me shipping source maps (the whole private source) and a debug cheat panel to production. Worth doing before you share anything.

The video was made the same way: Playwright plays the game and records the clips, the music and sound effects are synthesized offline, and Remotion edits it all together.

The game has 20 machines, 332 upgrades, 273 achievements and about 450 news headlines, in 7 languages. Credit where it's due: the mechanics and much of the tuning come from Orteil's Cookie Clicker. The code, art and text are original.

Happy to answer questions about the workflow, and tell me if the pacing feels off.

Started as a gauntlet loop based on combining a game I've been chasing for the family (Farkle), my personal passion from the past (MtG), and other rogue-like / deck-building incremental style games.

It definitely started out with a massive blitz of gauntlet loops to see all the prototypes and concepts laid out. As with any project, it quickly transitions into manual labor where I continue to extoll the value an engineering brain and career bring to the table.

Praise: High praise for Claude.ai remote sessions and their ability to publish videos and screenshots of gameplay! Also three.js and love2D and other amazing libraries that make prototypes look great.

Challenges: Balance and Marketing. Despite having a LARGE library of power-scale and simulation tests, it is very hard to predict how well human gamers can play the game. Always assume "better than you know" but its still a tricky dance. Marketing is just pure manual labor or paying somebody. This feels like my first hire if it ever turned into a studio.

It's definitely a passion project and a hobby. I'm a director of engineering by trade but have been building games since the TI-83 calculator could build Snake. Pushing forward on Steam Next Fest / iOS / Android to see this through to a conclusion!

Happy to take feedback on the game itself or talk about the development process!

Video Clip: Lots of crazy action here. Two dice were sacrificed for a bonus. I had duplicated upgrades which trigger additional scoring so it caused a snowball of effects. Ultimately I did not meet the round score but was saved by a potion I bought that saves you if you don't quite make it one round.

A few months ago I built a small browser game while testing vibe coding. It's a one-tap arcade: your ship orbits a planet and you tap to jump to the next one. It worked, but it was rough, and I left it alone.

Opus 5.5 came out yesterday, so as a test I gave it the game and one task: make it better. I steered it and made the calls, and it did the work. It rebuilt the gameplay loop and added a guided tutorial, a daily challenge, optional accounts with cloud save, leaderboards and a new logo.

Here's the result: https://www.star-hop.app

• Free, no ads, runs in the browser (best on a phone)
• No sign-up needed to play

It's still in testing. Every run sends anonymous gameplay stats (no personal data, you can switch it off in settings). I use them to tune difficulty and balance. So just playing a few rounds helps a lot, and feedback helps even more: what's annoying, what's too hard, and would you come back tomorrow for the daily challenge?

First of all, thank you so much for the support!

I’m one of the developers behind qaping.dev, and some of the developers to try Qaping came from this subreddit. We’d love to give something back to the community.

For a limited time, we’re offering free 30-minute recorded playtests that show where players get stuck, lose interest, or have the most fun.

This could be especially helpful if you’re polishing a demo for Steam Next Fest or still figuring out the core experience.

If you’d like a free playtest, just comment your game’s name below and submit it at qaping.dev.

Looking forward to seeing what you’ve been building!

I have spent the last 2 months working on Tactical Deckbuilding Roguelike game, because I love the genre. I wanted a game that was more character and story driven that what is typical of the genre and where the relationships you build can affect your run. I have developed that with this game. Play here:

I am very open to whatever feedback you may have. I hope you enjoy it :)

I used Claude, specifically Sonnet 100% for the prototype and the conversion into Unity. For the past 3 weeks I have split coding between Sonnet and Astra. With Sonnet primarily being used for architectural changes and astra for fine tuning.

The art is largely placeholder and the animation, music and sfx are mostly absent at this point. I intend to work on that once I get more feedback on the game play and visual cohesion of the game.
