Review: The Key of Dreams at Treowen Manor is a uniquely immersive experience

It is now a few days since I left Treowen, a gorgeous 17th Manor House set in the even-more-gorgeous Welsh countryside and I am still processing the experience. To call Lemon Difficult's The Key of Dreams simply an 'immersive experience' is to sell it very short. Where else can you spend 24 hours with the run of an entire house, crammed to the rafters with puzzles, clues to dark secrets and sinister rituals, where every decision you make may change the course of everything that happens next?
