Trama:

A horror job simulator where you work in the mailroom of a small regional office of Hell located in Modesto, California. You just started working in the mailroom of that weird building on 5th. The job was easy enough at first. Sort the mail and use their creaky old pneumatic tube system to send it to the correct departments. But then shit started getting weird. Can you figure out what's really going on in this place and find a way out?
