Kaidann

Kaidann is a short game about escaping a mysterious stairwell. After taking a new warehouse job with high hourly pay, you work overtime during your two-week training period and return home to find the elevators out of service. You take the stairs that no one else uses, and sense something is wrong as soon as you enter.

Follow the signs

A change occurs on some floors. Check each floor and follow the sign’s instructions: if you notice a change, leave through that floor’s door; if not, continue down the stairs. You must always leave through the usual door on the first floor.

Anomalies and endings

The game has 30 mutations in total. There are four endings: two bad endings, a normal ending and a true ending. Achievements vary with the bad endings, and each bad ending has its own achievement. The Complete achievement requires identifying every anomaly and exiting through the door on that floor; simply encountering an anomaly does not unlock it.

A playthrough can take 5 to 60 minutes.
