Urgent help wanted, as mention by Tonda in this talk. One of the lead playtesters really urgently needs a living kidney donor. Read www.iggyland.org and then consider reposting, please.

My talk is in one hour, here: www.youtube.com/watch?v=7eb-...

The nice people at ThinkyCon made me a poster! Also, don't forget ThinkyCon starts on Wednesday 5th - I'm on day two.

This is the most ruthless act of union busting in the history of the UK games industry. Yesterday, @rockstargames.com unfairly fired over 30 employees for union activity. We won't back down, and we're not scared - we will fight for every member to be reinstated.

ThinkyCon last year was pretty great, so mark your diary! Also, I'm giving a talk again... actually live this time. :-)

Don't tell the Git illuminatii I told you, but you can just type this into a shell: git config --global alias.uncommit "reset --soft HEAD^" ...and then when you want to reverse your last commit before you've pushed it, it's just: git uncommit ...which you might have a chance of remembering!

This game is so well made. Just a pleasure to play.

"iPhone build only bug"

The demo for Pieced Together is out! I've just been coding on this project, but @katekillick.bsky.social & @ellieeady.bsky.social at Glowfrog have done incredible work. Check it out, then give it a wishlist! (Reposts also welcomed. ❤️) store.steampowered.com/app/4005690/...

In Unity, a runtime script handling a prefab can add components to it. If it does, they stay there on exit. However, it cannot remove components "to avoid data loss". A classic example of seemingly reasonable design causing chaos... BRB, off to remove a few hundred duplicate components by hand. :-/

Have been watching this one for a while. Excited to finally get to play!

Really good intro to puzzle design. Worth bookmarking to share the link with new devs.

Sunken Stones is out! Had a lot of fun testing this one. Has some really nice character design, too.

Glowfrog Games, who I'm doing dev work for right now, are hiring for a few roles for Pieced Together (music/voice/marketing/animation). They're good people to work for. Here's the link: www.notion.so/glowfrog-gdd...

I think everyone should fill out the Bank of England's consultation on new banknotes designs and put "Dinosaurs!". If everyone did, we could have dinosaur bank notes. Do it! www.bankofengland.co.uk/banknotes/he...

For #thinkypuzzlejam5 I decided to try making an escape room. This was a lot of fun, but I would not recommend making an escape room in 48 hours! bateleur.itch.io/the-escape-s...

Oooh, interesting! Have to say, I'd find this very hard to do. Projects are always code-first for me because I like to get to something playable as soon as possible.

In less than ten days, I will be running Thinky Puzzle Game Jam 5. In previous years this has been a lot of fun and a source of many excellent games. It's not too late to sign up! :-) itch.io/jam/thinky-p...

I don't consider Blue Prince to be a puzzle game. This meets with various responses, but one person recently said: "It absolutely is, it's just that the initial room 46 quest is really before the start". Well... no. If over half of players don't get that far, it isn't in any useful sense the start.

👉🔴 Demo Announcement 🔴👈 I've released the Steam demo for The Button Effect! A first-person #puzzlegame inspired by The Witness, The Talos Principle, THE CORRIDOR, Antichamber and the architecture of a modern arts museum I enjoyed. Wishlist = ❤️ store.steampowered.com/app/3563110/

Exciting Spooky Express news - the demo is OUT NOW! 🎃 Plan the train route for the world's spookiest theme park. If you don't keep all the passengers on track, you'll have a grave problem... store.steampowered.com/app/3352310/... Check out the demo and wishlist on Steam!

Ah, Gentoo Rescue is out! I've been looking forward to this one but I won't have time to play until Monday... :-/

Very pleased to announce I'm now working with @glowfroggames.bsky.social on their game Pieced Together! It's a really strong team and the game's already looking great. Find out what it's about here: store.steampowered.com/app/2891370/...

Joel Fox has released a level pack for my puzzle game, The Golem. You can play it for free here: joel-fox.itch.io/who-took-all... Fair warning: the original is considered a hard game and this starts where that left off! It's really very good, though.

Announcing Spooky Express! Plan the train route for the world’s spookiest theme park! Pick up the monsters & drop them at their destinations. But be careful! Don’t let them bite the passengers or you’ll have a grave problem. store.steampowered.com/app/3352310/...

I am going to invoice @emmanewman.bsky.social for lost productivity this morning. :-P

I don't know if I could ever really manage to think this way, but this is how interesting design happens.

In response to the Polygon and Giant Bomb news, I created an indie and worker-owned games media starter pack. I’ll keep adding to it, so suggestions and recommendations are greatly appreciated. Please share!

My superpower: Not assigning any actions to my UI sliders, then wondering why they don't work.

Really interesting visual phenomenon I generated by accident: The only movement in this image consists of white and grey stripes at 45 degrees from vertical, slowly scrolling downwards. All the geometry consists of straight lines aligned to the axes.

Happy #screenshotsaturday! You could use some light-hearted fun, right? RIGHT!?!? Lab Rat launches in 10 days. Check it out :) 📢Wishlist HERE📢 store.steampowered.com/app/1304610/...

Good thing about garbage collectors: Not having to worry about memory management. Bad thing about garbage collectors: Worrying about memory management anyway, because otherwise you'll get a surprise GC when you don't want one.

Have played some of this. Would recommend!

Currently, AI is still terrible at writing, but one day it won't be. Now's the time to set the right precendent: no training on copyright material without a licence.

Oh Unity, why must you be like this? :-/

🚨Signal boost!🚨 If you worked at Blizzard from 1997-2006, specifically on StarCraft, Diablo, or WoW, I want to talk to you about Mark Kern. Same goes for Red5 employees. Our convo can be fully anon if you prefer, and we can chat via Signal, phone call, vid chat, whatever!

This looks like a really fun genre mashup.

I've said it before, but we're living through a golden age of puzzle games. The @thinkygames.com Thinky Awards had several categories where half the shortlist or more would have been worthy winners. My to-play list is getting ever more out of hand!

UDLR has a Steam page now! Smash that Wishlist button if you are so inclined! store.steampowered.com/app/3191170/...

Am I imagining things, or does opening Unity's profiler kick off a GC when running in Editor? If so, this... doesn't seem ideal. :-/

As it's now 2025 I thought it was time for a new CRT7 trailer showing off some of the weirder visuals I've been working on 🔊 Decypher strange computers, unravel modified tape players, and unlock impossible doors. Wishlist now: store.steampowered.com/app/2096780/... #GameDev #IndieDev #PuzzleGame

After a little more than two years of development, we are finally releasing our puzzle game "LOK Digital"! Made in collaboration with the exceptional video game developer @raindrinker.bsky.social and published by the celebrated @draknek.bsky.social . Mobile coming next year!

Ideas are much *less* important than you think. In seeing posts from designers online, I'm often reminded of this article written by Jamey Stegmaier: stonemaiergames.com/kickstarter-... The original idea is 1% - at most - of what makes a game work. Getting your idea to the table is much harder. 3/
