1:52:02longboolean Q: Not extremely important, (but Krampus related), just for your information, the word "lauf" in "Krampuslauf" is pronounced more like "ou" in the words "ouch" or "couch". Even less of an issue, in German the "a" in "Krampus" is more of an "ah", more like "Krahmpus". So... "Krahmpuslouf"

1:57:43flavioliraviolitest Q: Hey, just stopped in for the first time, this is really cool. Question is: How much time do you think game devs should spend refactoring code compared to writing new features? I often find it discouraging when I spend too much time refactoring spaghetti code without adding anything new for a while
