Heartless is a short psychological horror game that blurs the line between love and obsession, grief and madness. One year ago, Sarah vanished without a trace. The last place she was seen was Crimson Diner. For months, her husband, Jonathan, searched endlessly for answers until the trail went cold. But now, a letter has arrived. From Sarah. The message is simple: "Come to the diner." This time, he's not leaving without the truth.
