The rules in the world of the classroom are very strict. If you are seen walking around the class by the teacher, his field of vision will start turning from green into red. If his F.O.V. turns into red, you are caught and the game is over. The goal is to cheat from your companions who you will meet in the game. Please follow their rules to get to the end of the game. You cheat by moving your character with the cursor keys to your friend and then holding the left mouse button to start filling the cheat bar. The cheat bar will start to fill and as soon as it's filled, you have to get back to your place to finish the level.
