No live stream tonight. My family is taking someone out for a birthday dinner. If there is time, I may do a quick video of how the map tool is coming along but it would be a lot later tonight. #mythruna #IndieGameDev #indiegame #indiedev #indiegames

Join me at 9PM GMT-4 as I work on a map exploration tool for the scripting tools. I've want to scroll around a Mythruna map with custom map layers for a long time. Mythruna - Map Tools www.youtube.com/live/6iiZHVU... #mythruna #IndieGameDev #indiegame #indiedev #indiegames

Join me at 9PM GMT-4 as we add more detailed wind to the clouds. If there's time I may integrate it with the flora shaders so that the grass blows in the wind again. Mythruna - Cloud experiments pt 7 www.youtube.com/live/lZVL0ut... #mythruna #IndieGameDev #indiegame #indiedev #indiegames

Join me at 9PM GMT-4 to play with the cloud cellular automaton at least one more time. If this turns into a dead end then at least it's a very interesting dead end. Mythruna - Cloud experiments pt 4 www.youtube.com/live/EJ9hv7i... #mythruna #IndieGameDev #indiegame #indiedev #indiegames

Canceling tonight's live stream. Took a 4 day weekend to celebrate my birthday and heads-down code on Mythruna. This has left me in an odd spot to try to live stream in <2 hours. I will be more productive if I don't. Sorry, folks. #IndieGameDev #indiegame #indiedev #indiegames

No live stream tonight. In the middle of wrestling with design stuff that I don't want to put down or narrate as I work out these last bits. Also, it's technically a holiday weekend here in the USA so 'family time'. #mythruna #IndieGameDev #indiegame #indiedev #indiegames #ai

No live stream tonight. I pulled a back muscle and it's hard to sit in one place for very long. Also, while I got a lot done this week it was mostly one giant rig-scaling bug and not much visible progress. Back next week. #mythruna #IndieGameDev #indiegame #indiedev #indiegames

Something doesn’t quite belong. It stands apart from everything else, drawing quiet attention. The surroundings feel familiar, but one element disrupts the balance. This weeks theme, #OutOfPlace!
