Thanks for your feedback :)
The answer is quite simple, find yourself a nice workflow :)
I like to make my game mechanics really modular, this way you can get a lot of content done very quickly, ofc this approach requires a decent deal of experience and programming skills, but everyone can get there eventually. I'm still quite the junior myself, but I've been on my game dev journey for 8 years, so I gained some workflow feeting my needs by the time :)
