As we start all over again - it's time for the #pico8 #tweetcart tutorials!
The gen-art gifs must flow!
I'm trying to declutter my office, but it's tough to explain to myself that no, I no longer need Ubuntu and Hiren's boot on CD (both from 2012).

What if someone's life depends on me fixing a laptop from 2007?

The eye exam is the perfect game design. That big E is a great tutorial that teaches you the basic mechanic. But it doesn't baby you and quickly gets hard as they introduce the small and blurry enemies.

I don't like how VR is often put in the same row as crypto-nfts-genAI hypes. VR is a genuine medium and so many fun games, experiments, art and etc have been made in it.

Sure, it was hyped beyond its ability to deliver, but it really doesn't deserve to be treated like shoveltech.

Last year, I co-authored a book. I still find it pretty funny, taking into account the severity of my dyslexia. Still, to celebrate this anniversary, please enjoy this data and one of the chapters (apricot-shauna-11.tiiny.site)!

As I'm preparing a lecture called: "The Final Stretch:
How to Release a Game and Not Die in the Process", please enjoy this gif, from one of my old prototypes, that I found in the depths of my drive.

Buildingo was part of an exhibition at @amazefest.bsky.social ! It's amazing to see our little streamer in the wild (all by himself!).

As I'm preparing materials for workshops, I would once again like to remind everyone that this is the best GIF to teach about affordance.

I will not be taking questions at this time.

Thank you.

Happy holidays! May you spend this time with people that you care about and they care about you!
P.s.
Every year I make a cursed holiday postcard, so here you go.

Read the book and want to get a horrible drawing of an animal? You know what to do! But seriously, those things help a lot in this algorithmic world, so thank you in advance!

When @yeristr.bsky.social finishes working on our book, the year is 2023, November.

The Israeli attack on Palestine is in full swing. The Russian-Ukrainian war is reaching its second year. The world is on track for 2.5°C of global warming by the end of the century.

My favorite online bookstore added an origami pumpkin to the moral philosophy and weird sadness books order. I find it oddly fitting.

Our book (shoutout to @yeristr.bsky.social ) starts with considerations about games as a medium.

Calling Polish game devs! 🇵🇱

As more of us arrive here on Bluesky it would be great to re-create the network we've had.

Here's a Polish Game Dev starter pack to make it easier. Please let me know if I should add you or someone, and consider reposting for reach!

Do not start digging.
I wanted to create a little cavity for my greenhouse.
Max 30 cm.
It's 6 hours later, the hole is almost 1.5m deep.
I'm not done.
I yearn for the mines.
I don't know how this will end.

Titanic (2009) by Raf Peeters is a masterclass in physical design. It’s one of sequential movement puzzles - The goal of the game is to put all of the people into rescue boats. The trick is, that if the boat is full, it stops moving, and that's the only rule you have to remember.

Just got back from Video Games and High culture event in Bari. As always, though-provoking stuff, and as always, I found time to check on my favorite lion.
This dude is from Roman times, and all dignity got rubbed out of him by human hands and rain.
