I'm liking how this looks! I think, echoing the comments of another in this thread, it might be good to tighten down the number of complications and leave the last one as a stretch goal, just considering the time frame of the jam, but neal.fun games are a great place for inspiration!

Your document is clear, I do love "interactive infographics" to learn about things, and I really liked how you shared your doubts too (as a fellow solo dev, I relate :D) 

Another ref you could check if you don't know them already: Nicky Case's "Shtuff" https://ncase.me/ especially the https://explorabl.es/ they made some time ago. While they do provide lots of texts, they rely on simple interactions and are very effective. I also very much enjoyed their Fireflies simulation: https://ncase.me/fireflies/

Seems like a good idea. Though I believe you could add a couple of side missions to make it more enjoyable instead of sticking to just one mechanic of gameplay throughout the game.

It is unclear to me how dismantling industries would solve any problems, since industries are are providing food, medicine, clothing etc. to humanitiy. Besides, I wonder why the game would be fun to play. What is the game going to look like, what is the objective and which are the problems the player has to solve?

This game design document leaves readers with a clear understanding of this game's direction and alignment with the theme. I appreciated the note about keeping scope in mind and focusing on a specific gameplay loop. As a fellow solo dev, it's something that's top of mind for me as well. I'm thinking that, if necessary, you could even reduce the number of complications or "levels" while still delivering your important message. 

I also thought the point about music is well-taken. My push here would be to ensure that there are at least some sound effects, and perhaps some ambient background sounds that complement the narrative as players are moving through the game. Wishing you the best as we move forward!
