Click Death - Stick School Edition

You'd think as soon as the fire alarms started going off that the people in this stick school would start filing out of building instead of stepping over their friends' dead bodies to step into the flames. Although the Stick people never were too smart, are you smart enough to kill off all of these sticks in one try?
Slaughter the little stick people in bloody ways but remember there is one rule to this game, do Not let a stickman see another stick die!
