Hello Bluesky! Principia is an #opensource physics-based sandbox building #game featuring #electronics, #circuitry, #robotics, miniature robots, #puzzles, #Lua scripting and more. Starting its life as a commercial game by Bithack, it has now been released as #FOSS to be developed by the community.

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).
