The flashlight battery is at 10, but it will go away. Press R to recharge. Stay Away(get it?)from the red eyes, but the red guy won't hurt anything(except your eardrums).
I made all of this. The game automatically stops itself if your health is at zero(or less, which shouldn't happen). The red eyes will just go to your X and Y every five seconds, but they glide, so they can't turn at all.
