just follow the instructions on the screen.
The story is this: you and your friends were in a building for some reason, and then the lights go out. You need to go through the darkened building and find the power button to turn the lights back on. Have fun!:) PS: I checked it for bugs, but if you notice any new ones, please notify me immediately. Oh! also, you have to click the middle of the button for it to work. :)
