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:

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.

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.

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?

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!

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!

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.

For every level on the community site and the archive, you can press the Edit button to open it in the sandbox, look around and see what really makes a level tick.

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!

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.

In case you missed it, the new 2025.04.05 release of Principia last week reintroduces #puzzles as a new level type you can create in the sandbox. Create and play custom puzzles in Principia, just like in the old days!

Another one! PLANETS by TechZ is an adventure level with many planets to explore while travelling through space.

Principia level throwback! Freight Train by jasnsathome is a level featuring a very well built freight train which you can drive. But be careful not to overheat the engine!

"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.

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.

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 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!
