About
The Interval Bureau: Extension 0 is a short psychological horror game played entirely through a workplace hotline.
You are an employee of the Interval Bureau. You’ve forgotten your employee ID, and you need to recover it.
Call the Bureau. Navigate its extensions. Follow instructions. What begins as a routine administrative problem gradually leads somewhere much stranger.
There are no jump scares. The horror is in the language, the procedures, and what happens when you keep following them.
Around 1 hour, designed to be played in one sitting.
Fully voiced, with original hold music and ambient sound. Headphones recommended.

Great pick up
Short game but quite mysterious, the dialogues are well written and I could imagine the sequences pretty well. I enjoyed the FX + audio design, they made the scenarios more immersive. Anyhow, just wrapped up the last part, I have so many questions and want to know more haha

If you enjoy Choose-Your-Own-Adventure style books and a little creepy puzzle solving, this is a really enjoyable experience with excellent atmosphere and voice acting. short but I had a great time.
