This is my all-time favorite mobile app, and instead of spending money on the app, I bought it on steam [because achievements.] :B

You build an adorable town and little people run around squawking about the enormous angry bears rampaging around. And then you quietly murder all the bears and turn them into churches (do the people fear the bears? or do they worship them? Do they pay homage to their bones as we do to the saints?). And when you think "I'd be so much better at this game if there were no stupid bears mucking up my plans" you can choose the game setting where there are no bears, and realize - no. You are just bad at this game.

I have only ever gotten one skycastle.

Someday. Someday I will build a sky empire. Just watch me.
