About this game

"Minasoko no Kagi" (The Key to Everyone's Secret) is an escape game set in a nighttime aquarium.

On a stormy night, in an old aquarium with two weeks until closing time, you find yourself trapped inside during a power outage. Armed with a flashlight and a black light, you explore the dark exhibits, solving puzzles to restore light and water to the aquarium one by one. Bubbles floating in the tanks, water depths on the exhibit panels, scribbled directions—as you piece together the clues, you uncover events that unfolded in the same stormy night years ago.

The entrance is a little spooky, the exit is warm. Immerse yourself in the quiet night of the aquarium in this puzzle-solving escape game.

Please restore the lights by morning tonight.
