About this game

School, work, home—there are lots of places to play!

Enjoy the thrill as you try not to get caught!

Watch for the perfect timing to earn as many points as possible!

《Notice》

This game uses the controller’s vibration feature during certain character detection and interaction events.

Especially when playing with multiple players, we recommend using controllers that support vibration functionality.

The game can still be played with controllers that do not support vibration, but some detection cues may be harder to recognize.

《Rules》

One player takes on the role of the Watcher, while the others are Actors.

Actors earn points by sitting at desks or repeatedly pressing buttons at specific play spots.

However, if they are playing while inside the Watcher’s field of view, they will be caught.

The Watcher scans players within a triangular field of view and earns points by spotting Actors who are playing.

If an Actor is caught, they will lose points, so timing your actions carefully is key.
