The Classroom 3B demo only opens a small part of the school.

Today, I wanted to share a first look at the current development layout I'm building toward for the full game, planned for release on December 3, 2026.

The full version of Classroom 3B is being designed as a much larger, interconnected school rather than simply extending the demo with a few additional rooms.

The current layout includes multiple classrooms, science labs, an assembly hall and stage, library, computer lab, principal's office, administration and security areas, a central courtyard, a small maintenance basement, multiple floors, and a dedicated vent system.

CLASSROOM 3B IS ONLY PART OF THE MYSTERY

The classroom remains at the heart of the story, but discovering what happened there will take the investigation much further through the school.

Different areas are being designed around exploration, paranormal investigation, evidence, environmental puzzles, locked routes and supernatural encounters rather than existing simply to make the map larger.

FROM THE DEMO TO THE FULL GAME

The public demo represents only a vertical slice of the experience I'm building.

For the full release, my goal is to make the school feel like one connected location that gradually opens as you investigate it — with new areas, additional investigation opportunities and deeper evidence chains leading you closer to the truth.

This map represents the current development layout and may evolve as areas are built, tested and improved before release.

Thank you to everyone who has played the demo, shared feedback, created videos, or wishlisted Classroom 3B.

The demo opened the doors.
On December 3, you'll go deeper.
