I've finally finished my GDD. It's not perfect and it's my first time even doing one. I'm sure there are some major holes. But I got what I wanted from it. A taste of doing a GDD for a game that would qualify for the WoA 2017 contest and could be made in a week.
This was fun. I'll probably do some more "small" game like this just to get the hang of doing this.
I invite everyone to read it, critique it, and if it's real bad thrash it.
