Principia is a physics-based sandbox game featuring mechanics, electronics, robots, puzzles, Lua scripting and more. Originally released as a commercial game by Bithack in 2013 and later abandoned in 2014 due to financial difficulties, the game's source code was released in 2022 to be further developed by the community that grew up playing it.

The game is available for Windows, Linux, Android, with experimental ports to other platforms as well as being able to run in your browser. You can read more about the game and download it for the supported platforms at: https://principia-web.se/

I hope I am intelligible enough to be understood... otherwise enable CC.

Unless something unexpected pops up, a new release is planned by the end of the month. Be sure to test the new Dear Imgui dialogs to make sure it will be a smooth release!

What's important for this video is that it has a touchscreen and can be folded back to act like a tablet.

Recently I have been working on improving the touchscreen support on non-Android platforms, reworking codepaths that were hardcoded for Android to instead be controlled by the "Enable touch controls" option in the settings. This should improve the experience on Linux-based mobile devices that run something other than Android.

We start off by building a car with a emitter gun attached to it, then in the second one we solve a laser puzzle to keep a beam active while guiding robots to the goal. The third one is a simple Apparatus-style marble maze, and the fourth one is a simple circuitry puzzle.

The levels are all rather short in length and simple, so the video shows every level from 1 to 4.
