About This Demo

Afterschool Class Is in Session—and the Curriculum Is Deadly.

You thought Mrs. Glower was just your biology teacher. But when she invites you into her home, the lesson takes a terrifying turn. A sudden blackout plunges the house into darkness, leaving you trapped in claustrophobic chambers where the only thing between you and the unknown is a single candle.

Illuminate the Truth

With the house swallowed by shadows, every flicker reveals a new nightmare. Peer into the darkness to find what you need to get out, but remember—some things are better left unseen.

Arcane Investigations

This house is a tomb for secrets that were never meant to be unveiled. Use classic point-and-click logic in a 3D environment to examine your surroundings and piece together the tragic history of the Glower family. Discover the remnants of a master’s failed experiments and decipher the truth behind your invitation. But be careful what you unearth—some lessons demand a price that can only be paid in blood.

Survival Has a Price

You are not alone. As strange phenomena warp the reality around you, a dormant horror begins to stir. Something malevolent is hiding in the dark, a relic of a ritual gone wrong. Now, you must navigate the shadows while a desperate voice pleads for help. Will you answer the call?
