HOTARU: The Lost House

A beautiful Japanese house. A creature in the dark. A swarm of light to guide you home.

HOTARU is a first-person walking horror set in an old Japanese house known in folklore as the "mayoiga" — the Lost House. Once the door closes behind you, there is no way back out. Walk by firefly light. Listen for footsteps. Hide when they come close. Find the back gate before the night devours you.

— FOLLOW THE FIREFLIES — A swarm of fireflies drifts around you. The more you have, the wider your sight, the brighter your path. When a yokai draws near, the fireflies scatter and flicker — your only warning. Replenish them at andon lanterns hidden in the rooms.

— ONE YOKAI PER NIGHT — Each night brings a different visitor from Japanese folklore. The faceless Nopperabou listens for sound. The eight-foot-tall Hachishaku-sama sees too far. More will come as the nights deepen.

— HIDE. SURVIVE. ESCAPE. — Slip behind a folding screen. Disappear into a closet. Wait for the footsteps to fade. Then keep walking — the back gate is somewhere in the dark.
