Rooms for Improvement:
Multiplayer-Needs to have more gamemodes(Such as versus), and chat
Single Player-Needs another chapter (With new maps obviousy)
If you do these things, you've got yourself an even better rating and the proof to the community you can make good balloon games as well as zombie games.
This guy was helping my wife cheat. So I took a layer of skin off of him, painted the blood a skin color, used a chainsaw to chop his entier leg off, re-attached his leg, then colored any blood on him, and sent him back to work.
Technology tab in the research, job types, more plants to grow, winery, slaves, option to expand land for a price, seasons, upgrades that affect the house directly, and being able to view the family tree would all be an amazing addition to this game.
Ideas: Bigger town, deeper depth, more resources to mine, more upgrades, bigger costs, in game achievments, (Possibly?) combat, character customization, can directly delete save slots, a "create your own world" mode, more songs, elevators, and a home where you can store things that you've mined.
