In this tower defense game the monsters will climb the castle floor by floor until they fight your guard. You will need to assign various knight monsters to attack, shoot and freeze the enemies that are invading the castle. Each unit can be upgraded to increase their damage done to the enemies and spells can be cast for a price of coins to rain down a severe amount of damage for a small amount of time in an area of your choosing.
