The yellow guy is called Window Guy. If the Window Guy is at the window, you can scare him with a flashlight. The purple guy is called SuloExe. When SuloExe comes to you, just close the door. The orange guy is called Smile Guy. Smile Guy will slowly come towards you from the hallway. You can scare him away by looking at the camera. I should also mention Lightem, he knows how to hide in the dark very well. Check him with a flashlight from time to time. Good luck :)
