The Principia about page has seen some improvements recently, so I'd like to bring attention to it. principia-web.se/about It features a description of the game and its journey as well as game screenshots and logo. Doubles as a press kit for those who wish to cover Principia. #gamedev #gaming

Halftime for the current Principia building contest, Crazy Circuitry. One week has gone by, one week left! randomguy123 has submitted a solid contender today, a six digit random number generator. But what else will others submit this week? principia-web.se/contest/3 #gamedev #contest #competition
Screenshot of the random number generator level by randomguy123. It features a bunch of graphs and debuggers and the randomly generated number is visible on digital number displays to the right.

Earlier this week I pushed an update to the Principia site that merges the latest, most liked and most downloaded levels pages (both non-archive and archive) into one new page. That's six pages, combined into one now, with all sorting and filtering options right at your fingertips! #gamedev
Screenshot of the new level browse page, containing radio buttons to select whether you should see current levels or levels in the archive, as well as a dropdown to sort by (latest, oldest, most liked and most downloaded) and filter by level type (all, custom, adventure and puzzle).

Back in 2021 I made an iceberg image for Principia, full of references. I originally sent it in the Discord server and it was mostly forgotten about, but rediscovered it recently. I've now posted it on the forums w/ a full legend over the iceberg: principia-web.se/forum/thread... #gamedev

This year marks 15 years since the initial #Android release of #Apparatus, 1.0 being released August 2011. It was revolutionary for its time and reached immense popularity back in the day, topping the charts on Android Market at its peak and being handpicked as "Editor's Choice" by Google.

Today, another batch of fixes to the Principia web port were made. One of the things I fixed was rendering LuaScript sprites, making levels such as this rendition of the beginning of Star Wars ch. IV now fully playable in your browser without glitches: principia-web.se/archive/leve... #gamedev

And here you have some funny graphical glitches from when I was working on the web version. I'm sure it will improve over time. #gamedev

Yesterday the #web version of Principia has finally gotten into a state where it is relatively playable now! There is now a link on each level page that takes you to the experimental web version to run the level straight in your web browser, without needing to install the game. #gamedev

Interesting classic level from the old community site, Magma Chamber by zardOz 🔥👀 Can the robot manage to navigate across the dangerous depths of the lava pits? (Level: archive.principia-web.se/level/5627) #foss #gamedev #gaming

The new Principia building contest is now live! 🎉 The theme is Puzzles. In particular, the newly reintroduced puzzle level type of the game. Create the most interesting puzzle you can think of to win the contest. Good luck! principia-web.se/contest/2 #foss #gamedev #gaming

Last year I hosted the first Principia building contest after the game's open source release. Now we'll be having another building contest next week. The idea will be simple: Two weeks, one theme, build the best thing you can possibly think of in Principia. See you soon! #foss #gaming #gamedev

Don't know about the last one... But have a marble maze, made in Principia. Navigate the ball through the maze by shifting the gravity, like you were playing one of those mobile maze games. Guranteed victory. principia-web.se/level/14 #foss #gaming

To create some more activity there, I've recently begun posting picks of great levels I find from the wealth of thousands of uploaded user creations in the Principia community site archive. Browse, play and upvote your favourites! #foss #gaming

And of course, the classic Principia puzzle package still remains available, featuring 31 levels where you build contraptions of varying complexity to help robots reach the goal, through any means necessary. principia-web.se/classic-puzz... #foss #gaming #puzzles

"THE GIANT CHEWING GUM" by TechZ, the winner of the "What the hell is that?" Pro Contest back in the day is still quite an interesting adventure level, 11 years later. archive.principia-web.se/level/6713

Of course, extravagant circuitry isn't exactly a new accomplishment in Principia. One level I remember from back in 2014 is Rubicon's Simple Calculator level which implements a calculator that can add and subtract numbers. archive.principia-web.se/level/2108
Screenshot of Rubicon's Simple Calculator level. There is a calculator in the middle, and a large amount of circuitry surrounding it to implement the calculation logic.

Recently nomad on the Principia community site uploaded a level featuring what is claimed to be a turing complete computer. It certainly looks impressive, featuring an ALU and other components built with Principia's circuitry system. principia-web.se/level/1190

Principia 2025.04.05 has just been released! It brings many changes and improvements since the last release. The biggest one of them all is that puzzles are now once again available as a level type to be created in the sandbox and played from the community site! principia-web.se/news/19
