Lots, and lots of secrets, waiting to be discoveredGAMEPLAY:Tasked with printing out pictures (taken with an instant camera!) and placing them into a container, you must perform the same act around about 120 times... whilst being paranoid about the nightmarish creatures that await you outside your office. The lights occasionally turn off, and you must venture out of your comfort zone to restore it via a lever right outside.

Outside of your office (and sometimes in!), there are going to be nightmarish, shadow people that attempt to kill you. Use your instant camera to either A: kill them, or B: stun them and use your handy-dandy axe to kill them.

You need to plan your way to the lever to end the nightmare temporarily.
Or end it entirely...
