About this game
The developer's description, from the game's Steam store page.
This is a 3D walking simulator and loop horror game featuring characters from the "Tohoku Zunko Project."
Story and Objective
You have been trapped in a mysterious, reality-bending space. To escape this endless loop, you must observe your surroundings with extreme care and identify any "anomalies." Only by making eight correct consecutive decisions can you find your way to the exit.
Game System: "Marking"
Unlike traditional games in this genre where you simply turn back, this game introduces a physical "Marking" system.
- Observation: Inspect every corner of the room and the behavior of the characters for any signs of the unusual.
- Marking: When you find an anomaly, you must point it out and "Mark" it directly. The path forward only opens if you correctly identify the anomaly.
- Decision: Choose your path—go "Upstairs" if you found an anomaly, or "Downstairs" if everything seems normal.
Play Guide
- Winning Condition: 8 consecutive correct choices.
- Playtime: Approx. 20 minutes or more (depending on your observation skills).
- Controls: First-person action using mouse and keyboard.
