The moon, once serene, now portends doom. Air raid sirens blare, TVs warn: "Do not look at the moon." Your world's turned upside down. Messages flood in, all asking: How to survive in this world of bizarre rules?

In this eerie city, every step must be taken with caution, as every choice could be a matter of life and death. You will experience the myriad possibilities brought by "rules," which may guide you to safety or plunge you deeper into danger. But remember, there's no such thing as a free lunch; every decision you make will carry a corresponding cost, light or heavy, that cannot be avoided.
