Bloodmail: Shadow Courier のアプリ分析 2月2日

A single purchase unlocks the full story—no ads, no IAP, pure immersion. Everyone is thrown into a sealed iron chamber: eight letters, eight doors, eight strangers, and a chilling infant corpse on the table. The task seems simple—deliver each letter to the “person” behind the door. But the rules twist unnervingly: bloodstained letters can’t go to women, a man may receive only three, and you get one chance to name the killer. Worse, blood‑red numbers are carved on everyone’s back. As the countdown begins, pale hands drag someone into darkness. Death is not a threat but a reminder: someone lies, someone hides, and the real killer may stand among them.
