Hey there boundtotheearth!
I'm glad you enjoyed the jam! I always enjoy reading about the game development process so I was kind of hoping someone would do a post like this. I definitely agree that planning your game before you jump into it can make a huge difference both in terms of the final product and the dev process itself. You were spot on with the art making it easier to get the feel of a game right too.
I don't agree with the last part though where you say the game is trash, i think it's a fun game with a solid idea, the rough parts are pretty much to be expected from a game jam. I was also thinking about hosting another Last Minute Jam between October 28th - October 30th, but I'm not sure. If I don't host one then, I definitely will at some point in the future.
