This is an exercise in which you learn where to go and how to survive before everyone...disappears...yes...that's the word we'll use.
For those struggling, here's the strat: you can vaguely see where to go in the dark, so you only need the flashlight to fend off the monster. Don't continuously shine it, just blink it. If your flashlight is overloaded while the monster is on screen, it's game over.
A solid entry, and you'll grow as you continue to jam.
