Help the Keeper of the Magic Hammer protect the castle from enemies. You will face the representatives of four elements: water, fire, earth and air. Use their vulnerabilities to opposite elements by selecting the correct hammer.
Defend your castle by fighting off the enemies incoming! Level difficulty increases as you advance, so be sure to upgrade your units. Deploy knights, archers, catapults and more such as tower defenses!
The clockworks are attacking! Use your turrets to knock out approaching clockwork enemies. Don't let them reach the source well before the day ends or the battle is lost.
