I noticed people are having trouble being the Black Great Mage. Here is how: The Black Robe Leader will want you to capture a traitor. Capture him AND kill Iceroot. Allow him to show you where the person who makes the poison. After your cured, soon the Great Mage will want you to get antidotes for him. Later on, you kill him. Hurrah, your a great mage. Black of course.
Here is a tip for the game. Buy all the upgrades except the heart rate. When you are ready, buy the heart rate. Then hide. Make sure your sound is muted. What happens? At first, nothing. Then, a boy's face in black and white (to make it scary, it flashes) yells YEAH!! Hey, it increases your heart rate.
