The yellow man's name is Window Guy. If Window Guy is in the window, you can scare him away with a flashlight. But remember, if Window Guy is at the window, don't close the door. The purple man's name is SuloExe. When SuloExe comes to you, simply close the door. The orange man's name is Smile Guy. Smile Guy will slowly come towards you from the corridor. You can dismiss him by looking at the camera. I should also mention Lightem, he knows how to hide in the dark very well. Check on him with a flashlight from time to time. Finally, make sure there is no more than one character on the screen. Good luck :)
