I agree with the others; really interesting concept, but I think it needs cutting down a bit to fit the scope of the jam. I think a good idea might be to brainstorm which elements are the core that you want to focus on and then removing the rest for now. For example, do you need an animation for the drone taking damage? Do you need NPCs to be moving around the location or multiple quest types and minigames? You might decide you do, as it's integral to the feeling you want the game to have, but there's a huge amount of ideas in here - the foraging minigame on it's own could be a jam submission, as could the pizza one. It all depends on your team size and capacity, of course, and I'm interested to see what you come up with regardless.
The ideation document itself seems good, particularly the Introduction and Mechanics sections, which seem the most fleshed out and edited. I think the bullet point list under "theme" contains a lot of solid ideas that'd be great to see in the game, and I think utilising concepts like disaster capitalism will make the game's apocalyptic future a more interesting and realistic setting. Keeping the scale of the drone's missions small, as you've outlined (deliveries, communal gardening, cleaning solar panels, repairing relationships etc), helps to drive home your themes well while also exploring elements of local sustainability and anarchist theory. Looking towards real-life communities already building hope in the face of these challenges might help you think of more quest/setting ideas; for example communities like the Zapatistas in Chiapas and the Apoist Kurdish movement in northern Syria have focused on issues like restoring peace, creating seed banks, creating clinics to enable healthcare without access to hospitals, and creating self-organised systems of education. As you highlight in your theme notes, issues of social inequality are connected to environmentalism.
Good luck!
