About This Game

The Lost Study — a story puzzle escape room.

Restore a long-forgotten study by solving puzzles, collecting stories, and refilling its shelves.

Fourteen tales. Five protagonists. One world.

What you're doing changes with the story. Escaping a room. Running a place. Chasing a mystery. Just going somewhere.

Some stories connect openly.

Others seem unrelated until you look closer and find the thread running between them.

Over 60 chapters across 14 stories, 3 to 5 chapters each.

Airan was born a commoner and orphaned young.

Then, overnight, the House of Jonstina — the greatest ducal family in the Kingdom of Natalis — took her in.

My common birth already counts against me. And now the magic I use turns out to be banned here?

A survival story about a world where one wrong word costs you.

🔍 364. The Secret of the Blue Powder

Where does this end?
