■ Risk Flow: Greed vs. Survival
Every floor presents a choice: press deeper into DANGER for more experience and greater rewards, or fall back to SAFE zones and live another day. The Risk Flow system tracks your position—green means safety, red means death is near. Will you risk it all to grow stronger, or play it safe? One wrong step and your run ends. Choose wisely.
