The game is based on the Mines and Magic for StarCraft II mod/map.
You build buildings and farms around the castle to obtain resources and expand territories. Buildings can be upgraded, and you can use a rock-destroying beam to find new sources of resources (one use between each wave of enemies).
You can improve your castle (it will shoot various magics), buy spells for manual use and create units.
Creatures can be created only between waves. You won't have to buy new units to replace those that died (if they die, they come back to life before the next wave).
