Damn bro, nice.
How many builders do you have? I've only got 3, it takes ages for the larger upgrades to finish, so I've been slowly upgrading everything.
Are you in a clan?
Best way to sum it up, build shit and upgrade it.
It's a game that takes time to build everything, so it takes patience.
You can go attack other peoples bases and they can attack you.
While attacking others, you can gain their resources that they build up if you're successful in the raid.
In the aspect that the game is free, it's a dope.
Here's a video of it that I just found, pretty much what it looks like.
His base his pretty built up though.
