Great job,
Few thoughts, I m certain u planned on adding at some point.
a) for each animal, could the corn deplete -1 each day. ( not sure if u want to add a corn feeder, much like the water feeder)
b) for each fire pit, could wood deplete -1 each night.
c) for each companion part of my tribe , could food/water deplete -3 each day.
d) also could these status show. just like u have the power draining. This would make resource management more in-depth and challenging.
e) is their any way for cows/chickens/bison to auto die at about the same rate they are born, and be auto harvested by the robots, tribe mates, in order to keep the population under control.
f) Can u, while exploring other terrains on the map, add crashed cars/planes/trucks/tanks/missiles, so we can farm for metals, it would visually feel more in-depth.
g) Can u add oil Pumps, to work much like water pumps through out the map so we can harvest oil, and can you add an oil power generators stoves, use oil and generates much more power?
Thx an advanced, I just feel these additions at some point would make the game more subversive, and more challenging.
