Facebook game
There was a game I used to play on Facebook but I deleted the app from my page a few years ago, and I kind of want to play it again but have, of course, forgotten the name. The concept was pretty simple, basically you're the leader of a small medieval village/fort and have to upgrade the buildings using various materials to protect yourself against enemy attacks. I remember the buildings being in a circular formation with a lookout tower in the top middle part and a grassy area inside the formation.
