Try to steal free will from rebel people (yellow ones). Distract them with evil items while they are trying to convert good people (blue ones) with their terrible dance.
Left Click: Steal free will from everybody in an area.
Right Click: Distract evil people casting evil items, but take care! Good ones could be affected by them.
You win when everybody belongs blue, you would lose if all were yellow.
Good luck and stop that madness. Finish the Free Will.
