Awesome game, as I said before!
Players can sometimes say something interesting that can help to develop this great game. So I propose to write such thing here in that topic.
My 1st opinion is about quest (missions) system. There are many different things in that game that we can build and use. Would be nice if the main (tutorial) quest line will teach player how to build and use all of it. Maybe some buildings(/technologies) even must be hidden until player complete needed missions step by step. Cow farming is much more efficient then chix, it could be a little part of story line too. More powerful weapon could be allowed to construct when player have done something using weaker weapon. It could be more rewarding and self-explanatory quest system, I think.
