You are wellcome :) I’m not an expert at all, but this process works in my case hehe.
For the Trijam, I’m using only the structure of a GDD tailored to my needs, and I’m sticking to the essentials because I’m not making a proper game, just a playable project. There’s no need to create an elaborate document. It’s just a time-saver. Having everything written down helps you get straight to the point when coding.
Tell me if that helps you ^^
