■ Night Study: Korean Ghost Stories (Demo)

This demo contains the complete first night. Nights two and three continue in the full version.

A school with the lights out. A different survival rule for every ghost.

In Korean high schools, students stay after class for 'night study' — supervised self-study that runs until 10 p.m. You dozed off during night study. When you open your eyes the classroom is empty and every light in the corridor is off.

The front gate is locked. You need to find the keys and get out of the school. But something is standing in the way on every route.

■ What kind of game is this?

Learn the ghosts' rules and survive.

The girl from the next classroom stays still as long as you are looking at her. A voice calls from the last toilet stall. Every ghost keeps its own rule, and only by figuring it out — and acting on it — can you survive.

Face Korean folklore and school ghost stories.

Eight ghosts drawn from Korean folklore and school ghost stories. Every ghost you meet is recorded in the codex.

Uncover the truth hidden across three nights.

Why does this night keep repeating? Collect the 18 pieces of evidence left around the school and find out what happened here ten years ago.

Multiple endings and Nightmare Mode.

The story branches into several endings. Reaching a certain ending unlocks Nightmare Mode.

A night school that fits in 1.44MB.

First-person retro graphics, voices and music — the whole night packed into a single 1.44MB executable.
