It would be focused on gameplay and more advanced terrain modification: * resource mining * base building * crafting Stay tuned!Read full article on Community Announcements (d3e)AnnouncementsOfficial
Demo updated with improved camera
One more demo update made: Many were complaining about camera behavior, so I've changed it: now if something obstructs camera vision of character - we have this small transparent hole. It should be much easier now to navigate through the world Few other changes are: Improved hints for missions. Bridge mission made easier (more tolerant criteria to whether bridge is considered built) Changed lightning in Ovanox (the yellow world) Make sure to restart Steam to get the update! :)Read full article on Community Announcements (d3e)AnnouncementsOfficial
Updated demo released!
Thank you everyone, who touched the demo on its first day of release! I've gathered a lot of feedback - and here is a hot update, where most of the issues are addressed: 1) Polished character movement (even when the surface under you is terraformed, the movement is still smooth) 2) Polished camera and reduce depth of field 3) Improved hints (much more difficult to miss them now) 4) Improved text readability 5) Added new Quest 6) Added Radio - find Radio Tower, fix it and use M to tune to your favorite station. Now you have options to have Chilled, Super Chill, or Energetic Chill vibe in the game :) 7) Improved last quest, so that you won't miss the portal thing Feel free to get the updated demo on Steam (restart your steam to get the update, if you already have game downloaded).

Game announcement: we are live on Steam! :)
{STEAM_CLAN_IMAGE}/45084818/98ba48c9019f38e144a857f186089d88c5ba1eaf.png After years in the game dev industry since 2007, I'm finally launching my very first own game as a solo developer. The Great Fluctus is a humorous, adventurous journey through strange new worlds filled with quirky civilizations, trade, exploration, and lots of surprises. I started the game with all my love far voxel games and procedural generations, however I believe the genre is too focused on survival/crafting/base building, with other areas quite under explored - and that's what I try to change - as you see from the early content - game is more focused towards exploration & narrative, with very limited crafting mechanics added when needed. Check out Steam Page to learn more about the game. I'll be sharing news, updates, and behind-the-scenes insights regularly, and I'm super excited to answer any questions you might have! Your support means the world to me. Please, subscribe to the game, ADD TO WISHLIST, and join me on this epic journey through the cosmos! Thank you so much, and let's embark on this adventure together! 🌌✨Read full article on Community Announcements (d3e)
