Got a couple:
- Incorporate building aspects:
- Electric Fences
- Water tanks / towers
- Silos ( w/ varying storage capacities )
- Fridges
- Boiling empty pots ( over a campfire )
- Map ( shows whole base & more advanced maps can be built / upgraded after completing x missions to show whole wilderness discovered [ not showing any undiscovered tiles ])
- mailbox ( receives jobs, letters for help and receive rewards)
- post box ( send letters for jobs / hiring people )
- Game elements:
- Spices & / or salt (little white mounds)
- Food perishable (requires water to be boiled & food to be stored in fridge, seasoned with spices or salt)
- illnesses / food poisoning ( requires food to be cooked over empty cooking pot [ interactive to do multiple things from water to food cooking ] and if not health depletes slowly and stamina decreases as a result )
- Can only get better through medicine or small chance of getting better from milk (retrieved from cows instead of food, can be a less effective substitute for water as well )
- Medicine can be made in medical workbench ( requires completion of lots of missions to unlock but once it unlocks, users are more likely to get it from raw food - takes 8 - 16 taps to cook as well ) otherwise users buy from buy stalls or anchor rage.
- Merchants / traders: Sells and buys items to set user defined limits to insure scrap growth. ( Set amount to be sold & what is sold )
- Add oasis ( fake mirages )
- In exploration tiles, some farther out have mine shafts where you can explore underground and fight more difficult bosses.
- Also in exploration, more abandoned towns or bases w/ potential survivors (if saved) join your squad.
Quite a long post, but I think that this might help to improve some stuff...
Also maybe updating the menu UI w/ a help / how to play section which can be accessed while playing and in menu.
