Mage: Kingdom Defender

You are a mage that needs to protect his kingdom from attacking spirits. To control your mage, you need to be able to cast spells that will defeat the oncoming spirits. To do this, aim and click with your mouse to cast a spell on the spirit. If you need to swap your powers, use the left and right arrow keys. Pushing the up arrow will drop a mine. Pushing the down arrow will make your apprentice cast a spell, which allows you to attack more powerful spirits. If a spirit has a color, will be more affected by a spell of the same color.
