All the entries from Gamedev.js Jam 2026

Andrzej Mazur — Tue, 28 Apr 2026 13:19:15 +0000

Gamedev.js Jam 2026, the seventh yearly edition of the online web game development competition, ended up with 495 entries – that’s more than in the previous year, another year in a row!

In the 2025 edition we had 4614 developers participating on Itch who submitted 420 games, which is a solid 9% rate. This year, with 2782 developers and 495 games that doubled and jumped to almost 18%! Looking at the past years where that rate was around 5% you could imagine building games and releasing them is as easy as ever.

Check out all the entries following the Machines theme directly on Itch: itch.io/jam/gamedevjs-2026/entries

Thank you all for participating! Make sure to play and rate as many games as you can, and provide constructive feedback to your fellow devs, as Karma on Itch (a reputation system where your game’s visibility increases when you rate and comment on other participants’ entries) is still in place. After all the overall winners will be based on YOUR votes!

As always, the voting will end on May 9th, with the overall winners being announced the next day on May 10th, and results of the extra challenges (picked by dedicated experts) will be published on May 11th.

It seems the challenges this year were incredibly popular, as more participants joined them than ever before in the past:

Open Source by GitHub (216 games, up from 122)
Build it with Phaser (95, up from 68)
YouTube Playables (109)
Deploy to Wavedash (181)
Ethereum by OP Guild (15)

There might still be a few false positives as the data is based on developers marking the checkboxes themselves, but those numbers are still quite impressive nonetheless.

YouTube Playables interest form

Thanks everyone who participated in the YouTube Playables challenge. If you are interested in developing a game for YouTube Playables, head to this link to submit your interest. This is available for developers globally regardless if you participated in the YouTube Playables challenge or not.

Wavedash challenge extended

That said, those numbers can still be improved. We’ve heard some of you had issues uploading your entry to Wavedash (with the $2500 prize pool), and so if you submitted to the Wavedash challenge on Itch, but don’t have the game published on the Wavedash platform yet, you can still do it – the extended deadline is end of this week, Sunday May 3rd 2026, end of day your time.

New Unicorn level in Flood Escape

Andrzej Mazur — Thu, 16 Apr 2026 00:00:00 +0000

This year we had a few themes so far already: Love, Machines, and now it’s time for Unicorns and Rainbows. The National Unicorn Day is April 9th, but we’ve been busy kicking off Gamedev.js Jam 2026 last week, and so the new Unicorn level for Flood Escape arrives this week instead.

This is the eleventh level for the game that we’ve made all the way back in 2017:

Island, City, and Docks (May 2017 in the original release)
Christmas (December 2017)
Football (July 2018 for World Cup)
Arcade (November 2019 for MozFest)
Winter (January 2020)
Halloween (October 2022)
Badlucky (June 2024)
Valentine’s Day (February 2026)
Unicorn (April 2026)

Unlock this new level in the game or use the cheat code below to access it directly:

Have fun with our little unicorn and try to reach the end of the rainbow!

Enclave Games Monthly Report: March 2026

Andrzej Mazur — Thu, 02 Apr 2026 00:00:00 +0000

Last month everything revolved around Gamedev.js Jam 2026, the preparations to the seventh yearly edition are in full swing. Lots of prizes, partners, experts, and challenges were announced already, with more coming soon as the jam starts April 13th already.

Games

No, nothing.

Writing

Only a handful of posts mentioned throughout this report anyway.

Events

I’ve attended meet.js Summit 2026 here in Warsaw - it was the celebration of the fifteen years of meet.js in Poland, and good opportunity to chat with some old friends I haven’t seen in a while.

The upcoming Gamedev.js Jam 2026 have three optional challenges so far:

There are more to be announced, including YouTube Playables (still missing the prizes and experts) and Ethereum (main partner and all the details).

Other

My GitHub Star status was renewed for the sixth time, I’m really happy to be part of this group of talented folks, reminds me the good times of the Mozilla Tech Speakers.

I’ve posted celebrating Enclave Games’ anniversary with the logo minifigures as March 10th is the day the Enclave Games legal company was created all the way back in 2017, though it was a brand since 2012 already.

Plans for the next month

Run Gamedev.js Jam 2026.

Sixth year of being a GitHub Star

Andrzej Mazur — Thu, 26 Mar 2026 00:00:00 +0000

My GitHub Star status was renewed for the sixth year making it quite the journey already since the beginning all the way back in 2021.

Here are all the announcements so far:

[2021] Becoming a GitHub Star
[2022] GitHub Star status renewed
[2023] My GitHub Star status renewed again
[2024] My GitHub Star status renewed for the fourth year!
[2025] Fifth year of being a GitHub Star

Can’t say much beside I’m honored (again!) and genuinely really happy. As always, if you’re curious how it all started and why I ended up being a GitHub Star, you should definitely check out the first post for details. Also, go through my report from GitHub Universe 2025 and expect to meet me at the 2026 one this year.

Open Source challenge in Gamedev.js Jam 2026

Andrzej Mazur — Thu, 12 Mar 2026 16:00:33 +0000

The upcoming Gamedev.js Jam 2026 starting April 13th will have a few optional challenges – the first we’re announcing is the Open Source one where you need to provide your source code on GitHub to participate.

Provide the source code of your entry on GitHub in a readable form to have a chance of being featured in a dedicated blog post on the GitHub Blog.

We might, or might not end up with such blog post eventually as after three years between 2022-2024, the 2025 edition didn’t get it. Fingers crossed, I’ll do everything to have it published this year though!

The prizes are the same as in the previous edition:

5 × GitHub Copilot Pro for individuals for 12 months

We’ll have a new expert picking the best games this year: Stacey Haffner.

She’s the Director of Microsoft’s Open Source Programs Office and leads game developer advocacy, so you’re in good hands. The whole challenge is still under the watchful eye of our very own Lee Reilly from GitHub though.

Enclave Games Monthly Report: February 2026

Andrzej Mazur — Mon, 02 Mar 2026 14:17:13 +0000

Finally a truly positive month: we’ve shipped the js13kGames 2025 t-shirts, released a Valentine’s level in Flood Escape, and started the countdown to Gamedev.js Jam 2026.

Games

Not quite the new game, but we’ve spontaneously released a brand new level for Flood Escape: Valentine’s Day. It went out on the 14th in the evening, but I guess it’s better this way than doing absolutely nothing.

It adds to a growing list of various thematic levels, and it’s fairly easy to add new ones.

Writing

Wrote a few pieces this month, including two longer articles: about Warhammer and the Enclave Games’ summary of 2025.

[13.02] Countdown to Gamedev.js Jam 2026 and call for partners
[14.02] New Valentine’s Day level in Flood Escape
[19.02] I went all-in into Warhammer
[26.02] js13kGames 2025 t-shirts shipped
[27.02] Enclave Games in 2025, and plans for 2026

Events

On the 13th I’ve started the countdown to the seventh edition of the Gamedev.js Jam, though given all the catching up I didn’t do much after all. Hopefully that’ll change in the coming days.

After a couple of delays, with extra steps in the process, and much needed help, the js13kGames 2025 swag was finally shipped!

Other

I wrote in Polish about me confirming with the diagnosis and getting official papers that I’m in the autism spectrum (Asperger’s syndrome), same as my daughter.

Plans for the next month

Focus on the Gamedev.js Jam 2026 preparations, attend meet.js Summit 2026 in Warsaw.

Enclave Games in 2025, and plans for 2026

Andrzej Mazur — Sat, 28 Feb 2026 17:24:24 +0000

Last year was quite similar to the previous one as unfortunately no new games were released, but at least it was quite similar to the previous one as all the usual events and activities were organized more or less on time.

The fact that the Yearly Report is out at the very end of February instead of the first week of January tells you a lot already, maybe I’m not past the burnout yet, or maybe I simply have too much on my plate. Anyway, let’s focus on summarizing the twelve months of 2025.

This is the eleventh Yearly Report already - make sure to check the previous ones if you want to learn more about our history: 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, and 2024.

Let’s start by reviewing the plans I had a year ago:

BACK TO MAKING GAMES! If I don’t build and release a single game in 2025 I’ll quit calling Enclave Games an Indie Game Development Studio and start calling it Event Organizing Company instead. Rebranding to Enclave Events I guess.
Usual stuff with Gamedev.js Jam 2025, Gamedev.js Survey 2025, Gamedev.js Weekly issues, and js13kGames 2025. At least that went ok, though the Survey was conducted in the last possible moment in December just before Christmas.
More involvement in OP Guild, exploring all the possibilities with Arcadia and OP Games. OP Guild ended abruptly after a few months, so there’s that…
Check out Telegram, Discord, LinkedIn, and other platforms accepting web games, and try to submit my own (hopefully brand new). Nope, zero.
Write the js13kGames history ebook. Not a single chapter.

Barely one out of five. I’m starting to think making plans makes no sense whatsoever.

Now, a quick recap of 2025, month-by-month:

January: Gamedev.js Survey 2024 Report, writing on the Gamedev.js site (10 articles)
February: js13kGames 2024 t-shirt shipped, more writing (18 articles)
March: W3C Loading and Control Community Group, new blog engine on Astro, even more writing (21 articles!)
April: Gamedev.js Jam 2025, a bit less writing on Gamedev.js (12 articles)
May: Gamedev.js Jam 2025 winners, js13kGames shader
June: OP Guild on hold
July: js13kGames 2025 preparations
August: js13kGames 2025 start, Online category
September: js13kGames 2025 deadline
October: js13kGames 2025 winners, GitHub Universe
November: Devconnect, ETHGlobal with Bober River Flow
December: Gamedev.js Survey 2025, Wawtech

Let’s look at the past year in detail and see what happened to Enclave Games in 2025.

Bad things

Absolutely no traffic in our t-shirt Shops, but that’s what you get if you put zero effort into marketing. Same for the speaking gigs I guess. I’m going to skip those two in next year’s summary for sure.

Still no games, and almost no usage of the GitHub Copilot I have access to. One simple demo of Bober River Flow made in a couple of hours throughout the whole year is definitely not enough.

Leading OP Guild as part of the OP Games cooperation ended in the first months of the year. I’m thinking of trying to revive it on my own though, especially given the upcoming Gamedev.js Jam 2026 will have the ETH Challenge.

I’m still struggling with crippling procrastination and lack of motivation, which is weird since I’m working on whatever I want and whenever I want as part of running Enclave Games. It involves my passion, making games, so what’s the problem? Something is definitely not right.

Ok things

Wrote lots of news pieces on the Gamedev.js website, but after a few months I had to switch focus to the usual: the jam and the competition.

Gamedev.js Survey 2025 was open in December, again. Better late than never! I did set the date for this year already to be around js13kGames 2026 though.

Good things

The Gamedev.js Weekly newsletter, even though happened to be out a day or two later than planned from time to time, generally was being emailed to subscribers every single week in 2025.

Gamedev.js Jam 2025 was a success with the record breaking number of participants, entries submitted, and votes cast. Lots of cool games to play, so definitely check those out.

The js13kGames 2025 competition went well, and we even introduced the new Online category with the support from Cloudflare.

Not only I was able to visit San Francisco for GitHub Universe, but also got the opportunity to fly to Buenos Aires for Devconnect 2025, which I really enjoyed.

I was involved with, and ended up on the printed boxes or their rulebooks in all the Neuroshima Hex projects released in 2025. I also dived deep into Warhammer.

Plans for 2026

Build a game with GitHub Copilot, using Phaser, in VS Code, preferably via the 100 Days of Vibe. It could even be expanding on the Bober River Flow demo or something similar.

Don’t forget to run Gamedev.js Jam 2026, conduct Gamedev.js Survey 2026 NOT in December, send Gamedev.js Weekly newsletter issues regularly, and run js13kGames 2026 without (major) problems.

Write that js13kGames ebook, or don’t. Maybe it’s not meant to be.

js13kGames 2025 t-shirts shipped

Andrzej Mazur — Thu, 26 Feb 2026 22:57:33 +0000

It seems having issues with the shipping is our yearly tradition, but I didn’t expect politics to come in and mess with the process. That’s exactly what happened this time, beside a few absolutely relevant problems we also encountered along the way.

Let’s start with the good news: the packages containing the t-shirts, long awaited 3D printed dice, and our usual stickers were shipped! Some of you close to Poland might start receiving them next week already.

The bad news? Our Polish National Postal Service decided to not only increase the shipping costs (again) by 50% (this time), but what’s more, all the folks living in United States of America will have to wait for their stuff a bit more. Why? Because Polish Post halted shipping to US indefinitely and blamed it on Trump’s tariffs. I can ship the package around Europe, to Australia, or Mongolia, but not US anymore. Oh, and apparently Colombia as well, but they didn’t even care to tell me why in this particular case.

The single vendor that still ships things to United States from here is FedEx, which costs multiple times more than the Polish Post, about $60-$120 per package, depending on its details. And that’s for the smallest one, with a single t-shirt, via the economy service.

I thought I’m either not going to ship the promised swag (27 packages) at all, or (more likely) go bankrupt. Luckily enough, our very own Ben Allfree stepped in and saved the day. A box full of (already prepared) packages with t-shirts was shipped to him in Nevada, and when Ben receives them, he will then send every single package individually to each of you via the local postal service.

Hopefully you’ll get your swag soon, but I’m seriously considering ending the t-shirt shipments going forward given how time consuming and costly it all became. I know it’s our tradition sice day one in 2012, but it’s really difficult to keep covering all the increasing costs.

Anyway, if you do receive your t-shirt please share a selfie! You can either send it to us directly via email, drop in Slack or Discord, mention the @js13kGames account or use the #js13k hashtag on social media so we can see it and add to our Facebook gallery. Seeing our design all around the world means so much to us, thank you!

Countdown to Gamedev.js Jam 2026 and call for partners

Andrzej Mazur — Fri, 13 Feb 2026 20:49:27 +0000

In exactly two months from now the seventh edition of Gamedev.js Jam, the online web game development competition, will begin. You’ll have thirteen days between April 13th and 26th 2026 to create a web game on a given theme announced at the start - we’ll have plenty of prizes to win and challenges to pick from.

Join us no matter your skill level - this game jam is a perfect opportunity to create your very first game, or build a prototype for your next commercial hit. Almost two weeks of development time should be more than enough!

I’ll start announcing everything soon, we do have a few things confirmed already, but if your company would like to partner with Gamedev.js Jam 2026 and support our web game development community, please get in touch! Recruiting new developers, promoting your own product, inviting folks to your platform, or anything else really - I’m always happy to discuss any ideas you might have.

If you haven’t done that already, please join Gamedev.js Jam 2026 on Itch, follow the jam’s account on Twitter and Mastodon (or even my personal one on Bluesky where I share gamedev news as well), and join our Discord to talk with fellow devs, and create or join a team if you don’t want to go solo. I can’t wait to see what you’ll going to build this year!
