i don't think that username fits you then lmao
it's free on halloween lol
it's just a horror element, a lot of horror games ask for permission to use your camera or webcam, or ask for your location or anything like that. all of that is fake, this is completely safe. hope this helps :)
if the light turned on then it turned on the webcam (don't worry, the game doesn't do anything with your face, it's just a horror element)
