Love the game and all it has to offer, lost my Save file after getting a new PC but ill see that as an Opportunity to play trough the game again.
Just want to say that you are doing an amazing job.
And a Idea i have is adding a Chest in the Finished Home or the Cave for storing stuff like Food because the "Inventory upgrade" is nice and all, but i think a chest (which you could get as blueprint for the cave or as bonus for Maxing out the House) would be a nice quality of life change. But thats just an idea
