Firefly Zero is made without any AI whatsoever. It also has no DRM, no subscription, no ads, no data mining, and no proprietary code. It's not just a technology. It's a manifestation of our principles, a statement that we all must do things differently to build a better world. #NoAI #zuzai #linux

Free game assets for everyone! We've set a small budget for promoting gamedev and supporting artists. And we've figured we can do both if we buy for y'all a bunch of game assets. 1/2

All our games have been moved from Github to #Codeberg: codeberg.org/firefly-zero No love for Microslop 💔 All other code (firmware, system apps) is still on Github. This might change in the future.

All the art for Firefly Zero is created not by AI but by a real artist. Alena is an author of 2 books for kids and a very talented illustrator. She created our logo, mascot, concept art for documentation, and splash screens for all system apps and the majority of games. www.instagram.com/alpo.nl/
