I don't think this game needs things to fight or whatever. It needs more functions and upgrades on the matter of getting more food or getting it better. Also, it would be really cool to have a vision inside of the colony.
I dislike the fact that the game has an end. An option to keep playing after you are done with the quests and war would be nice. Would keep me for some minutes until I finally get bored. But the game gets you on improving and leveling up, I don't see a reason to just kill the thing.
