To get the angle between two points: atan2(y2 - y1, x2 - x1). Yeah, there isn't much else to it. Just beware that atan2 returns the value in radians, so you'll need to convert it to degrees (or whatever your game uses).

EDIT: atan2 assumes Y goes upwards and angles are counterclockwise. If either (not both) of these is true, you should use y1 - y2 instead to invert the angle.

EDIT: oh, and if Y is positive downwards instead of upwards, you'll need to use y1 - y2 instead, since atan2 assumes Y goes upwards.
