"The Rules Kaidan: Night Watch" is a side-scrolling horror adventure game. In the game, you become the protagonist of these strange rules, navigating a world teeming with supernatural creatures. Your survival in this dangerous realm hinges on meticulously adhering to every single rule.

If you forget, death will be your teacher...

Obey the Rules, the Only Path to Survival

Understand and memorize the distinct rules of each world, as they can sometimes be completely opposite. Never enter the realm of rule-based anomalies with a habitual mindset.

Even when your soul trembles and your heart nearly stops, remember this: obeying the rules is your only way out.

Chase and Evade, Life Hanging by a Thread

Death does not visit when you are fully prepared.

No one will passively wait for you to reveal a flaw forever, and neither will they. As the exploration deepens, the night devours the last shred of sanity, and indescribable entities will actively seek your presence.

Between pursuit and flight, fear can easily overpower reason. In such moments, can you still recall the one rule that can protect you?

The Iceberg Topples, Strange Tales Emerge

Fear is humanity's most primal and instinctive emotion. After we built a great modern civilization with reason and courage, did those spine-chilling entities vanish without a trace? Or do they lurk beneath the iceberg, waiting to devour the next curious soul?

We drew inspiration from countless urban legends and modern eerie tales - phantom buses, sprinting mannequins, the cat-faced old woman... Any of them could become part of the world of rule-based horror, awaiting your arrival.
