Castle Keeper

Hilltop defenses stand between the kingdom and a marching army. Castle Keeper places an archer above the walls with infantry squads closing in from below. Enemy waves press toward the final line of defense. Siege ladders rise against the stonework, and magic joins the fight with freezing blasts or fire spells. Golden keys appear during the defense. Treasure chests wait for them. New fighters also become available, including a wizard, a sniper, a ninja, and an imperial stormtrooper.

How to play?

Draw the bow and fire into approaching soldiers before they reach the wall. A cleared wave triggers a choice between three extra skills. Coins from battle raise your combat stats for the next fights. Pull down siege ladders before attackers climb over. Cast spells at packed groups when the road fills with enemies. Use collected keys on chests to claim the reward inside.
