Lights Out

You wake up in a house that isn't yours stranded in the middle of the woods. The power mysteriously goes out for no apparent reason so you grab a flashlight and find the electric box to turn it back on. You find out that its locked. So you have to find the right key. But little do you know there is an Entity thats strong in the dark and weak in the light thats stalking you. You can use your flashlight to scare it away but it will come back. And just know you have limmited battery on your flashlight so always grab a bettery if you see one.
