I have created a technical video showing how the world (and future worlds) are generated for the game. I plan to create more developer blog videos in the near future as well. Also, be kind as this is the first video I have created in a very long time!

I also plan do to tutorial videos closer to the release of the game, so stay tuned for those also!
Enjoy!
