◆What is INOKORI -Isolated Hours-?

A 3D horror game. Clear your tasks and leave the office...but strange, unsettling phenomena keep getting in your way...

◆Task List

You can clock out after completing these 3 tasks:

Make sure to turn off the monitors, shut down the A/C's, and switch off the lights.

These are spread throughout the office, so try not to miss them as you make your way out.

◆Strange Phenomena

Phones ringing of their own accord...chairs spinning...floating objects...

These anomalies will take their toll on you if not dealt with so handle them quickly!

◆A Stranger Woman...

This strange entity stares directly at you...

Staring back is dangerous, so avoid eye contact.

It's said she goes after those who get too close...so keep your distance...look away...and leave...
