Press S to skip the call, and get ready, because you'll have to be fast.

First off, every time you hear the bell, that means that Hourglass has either respawned, or spawned in.

If he's in your office, first flip the camera ASAP. And turn off a camera. Any Camera.

If that doesn't drive him away, turn the light off and stand still.

Make sure to do this fast.

Also, yes his name is hourglass, i'm pretty sure.

I Prefer to call him corruptus, but..eh
