Then you reopen the upgrade screen, spend your gold, and go again, stronger. Your castle fights. You decide how. Four tower types (archers, cannons, lasers and shockwaves) that aim and fire on their own. Allies (archers and hunters) that march out of the castle and patrol the whole map.

Your cursor is a burning halo that acts on its own, continuously, and every element you unlock stacks on top of the others instead of replacing them. Fire : anything you sweep over catches alight, and burning bodies eventually detonate into their neighbours. Ice : a...
