Wow, this game is big. I had some issues with the save feature, but it's probably on my end. This is the kind of game I'd like to play over a few sessions.
Some thoughts:
- Cool splash art at the beginning
- I wasn't able to figure out how to send people on expeditions, and also I couldn't get enough seeds to progress my base (I needed 10 to be able to build a garden).
- For a new player, it's a bit confusing to figure out what each area does. Perhaps it could be useful to leave the name of each area permanently one, and show the details when the player hovers over it.
I think you have a good prototype for a very interesting game here. Keep at it!
