Blackboard Darkness is a survival horror game where you play as a teacher who wakes up alone in an empty school classroom at the end of the day. Following the trail of a missing student, you uncover a hidden entrance to a secret underground laboratory buried beneath the school.

Below, you will face a nightmare: the lab is inhabited by petrified creatures that freeze completely in the light. Your mission is to locate and rescue the student, who is trapped somewhere in the depths of this facility.

Your survival depends on light. You can use a flashlight, activate stationary lamps, and control the laboratory's lighting system to immobilize threats, power mechanisms, and open paths forward. However, power is limited—every light source can fail.

Explore the dark halls of the laboratory, uncover logs and data entries that reveal the history of dangerous experiments, and search for backup power sources to sustain the light. Every choice matters: spend energy to secure your immediate surroundings or conserve it for the final push toward escape.
