I can see that you planned out this production reasonably well, and that you're already started on the prototyping. I noticed that this is a solo project, and from what I've read in regards to art style and narrative I can see this scope being doable. I think the pixel art style can work, and the example of Octopath Traveler does give me a good idea for your approach. Although I do want to ask how many levels you plan on having for your game? I'm asking because it'll allow me to better understand your scope for the game, and seeing that you plan on crunching your game does make me concerned. Please pace yourself, it's fine if you're only able to have one level by end of the jam. I will be impressed with how much you can get done either way. One recommendation I will make is to maybe have the background show the current state of the world, or maybe having player looking out on the ruined world. I think this could help flesh out story of what happened to the old world as I believe just telling the player what happened isn't enough to show the effects of geoengineering. I would also recommend adding some stealth mechanics to the game. Seeing how the player can't fight back against the drones, and must start over if caught, I think it would be good idea to have spots for the player to hide from drones so it would be easier to move around without being caught. Aside from this, I think your game sounds fun and I look forward to playing it. I never heard of SRM, and would like to learn more about how it can used for good instead of harming the environment. I look forward to seeing what Everlasting develops into, and can't wait to play the final product no matter what form it takes.
