On my most recent developer stream, I dove into the not-so-simple process of preparing my PC-based game jam entry, Cat Trick, for release as a mobile title. There were lots of technical things discussed, but I think the most interesting and insightful segment of the stream was the last part, where we discussed how a lot of design and format decisions depend on the clarity of my goals for what I want out of this game. I recently went over my decisions with my teammate, Will, and since we were in agreement in all of them, I decided to walk through my entire decision-making process here.
