a. Yes food mechanic will be added. Basically water replenishes the resource they produce and corn will replenish their health (which will slowly deplete over time.
B. I've thought about that maybe the fire slowly get less bright and needs to be refueled.
C. Yes this will happen. Probably soon. See one of my previous dev logs about it.
D. Yes i will probably show a daily resource drain some where.
E. There is going to be several management items to set limits and do more micro manage stuff for those that like it. I just need to think about how it will work for those that don't.
F. Yes that mechanic is in place already. I just haven't added much to it yet
G. Yes I've gone back an forth about this. I've thought of just pure pumps that slowly get oil or turning corn into oil or having locations on the map you have to repair or refuel and defend over several waves of enemies choosing to risk a harder wave or leave with what oil you got.
