In all honesty, I'm incredibly confused. The cover image, itch description, and GDD are incredibly hard to digest and understand what exactly you want your game to be about as well as what the loop is. The way AI structures its writing is most likely the culprit to this, and your GDD, as well as future submissions viewable to others, would benefit largely from it being written by people to better communicate effective, simple, and concise ideas. From what I did understand, this appears to go from a survival game to a tycoon one, which needs to be handled extremely carefully in order for the themes to not entirely go against that of the jam. For the gameplay loop, actions are listed, but not how they're done, making what the player actually does mechanically to be left ambiguous. Also, even with AI assistance, I don't believe that what's being proposed is feasible within 6 weeks. Just the section talking about how a "one year crisis is divided into 24 strategic moves. Each move is 15 days, and in each move Tyler has a hard ceiling of 24 Capacity Units of stamina to spend." is an incredibly ambitious undertaking from a technical level, so I'd be wary of that.
