Something that would be great is if potatoes produced less and filled your food a little more because being able to plant 3 in a box and then getting 6 back cluttered up my inventory and made it a little too easy not to die of hunger especially when I put down multiple boxes.
Also more uses for scrap like weapons, reinforcements, traps, that sort of thing
One more thing in my opinion would be that the poles should let you build out 2 floor pieces instead of 1 and there should be some way to move/ pick up poles and other building pieces after they are put down
whether you implement any of these things or not, your game is super fun and I will make sure to buy it when it comes out
