In-Game

A horror dice roll adventure inspired by the Cthulhu Mythos. Much like in a tabletop RPG, "abilities," "luck," and "dice rolls" influence the story's progression. The protagonist is cursed on an island in the Seto Inland Sea. Investigate the island, uncover the mysteries, and break the curse!
