Když jsem naposledy (asi v 15) krouhal zelí, z bílého zelí bylo červené a můj prsteníček je už jen 99%... Tak bacha :D

This is lovely. I wonder what the FP invariant is - typeclass laws?

Things are going well! I could stop now, very happy with how it turned out. TODOs (maaaaybe): * reading Tiled maps * interactivity (signs, doors leading to other maps) * multiplayer * plugging the game into the amber CRT * blogpost or a short video? * extract a library for future game jams etc.

Got a tiny top-down RPG prototype going to learn more about WebGL. All the conversions between coordinate systems are still a bit confusing, but I got it done! github.com/Janiczek/rpg...

Finally finished @desktopexplorergame.com on like third or fourth sitting. Yo what the f, it really picked up pace and emotions towards the end. Really lovely. Also, nice easter egg :)

Decided to do something about the Aseprite editor I have open since 3 weeks ago. God I hope I'll get better with time 🙈

<im-in-this-photo-and-i-dont-like-it.png> Should I put a hard "I'm going to release it on $date" limit on NuAshworld to force myself to cut scope and not procrastinate on the important stuff? Ughhhh it makes sense but...

Drawing is hard! I have a new blogpost, about an aha-moment from reading the book "Thinking in Systems": martin.janiczek.cz/2026/07/24/s...

This was very fun. A hands-on example from the book Thinking in Systems, illustrating how the intuitive solution to a problem can make it worse. Longer delays?! github.com/Janiczek/thi... martin.janiczek.cz/thinking-in-... I'll write a blogpost with the explanation and main idea later.

Some letters will need tweaking after seeing them in context, but so far this all went surprisingly OK!

Nothing a little WebComponent and calc-size(fit-content, round(up,size,2px)) wouldn't fix babyyyyy

Shoot, some of the things still don't line up with the pixel grid. This is a whack-a-mole I wouldn't need to solve if I was on a canvas or WebGL

Death to fractional pixel positions! It's IMPERATIVE I get crispy font pixels. You can even do that with CSS transitions/animations! Check out steps(): developer.mozilla.org/en-US/docs/W...

predictable authenticity rant incoming Read this somewhere and can't find the source anymore: "I'm much more interested in anything you write, however bad you think it is, than something AI wrote" I think it goes for anything: blogposts sure, but also music, websites, games, presentation slides..

Whoa!!! One of the developers of the original Ashworld replied to my post on a forum and I didn't notice for a whole year. Super cool lore dump!
