This thread is a cool idea!
We have some stuff in common because this is my third game jam too. The way I approached this jam is... work as many hours as humanly possible and shove as much content as I could into the game haha. The first day was brainstorming and setting up basic systems like save/options and then trying to figure out how out the scope. I forgot the cardinal rule of programming though and didn't cut my scope in half, so I was really struggling to get everything in on time and barely made it.
This was my first story-based game so it was difficult to transition from a mechanics-based perspective but I am decently satisfied with the result. Feel free to check it out here!
