This game is written in Robin Johnson's own engine, one of the best home-brew parsers available. It is a Scott Adams-style puzzlefest, with smaller room descriptions, lots of places to explore, and 0-1 items in each location.
Some of the puzzles are quite hard; this game is for fans of old-school design.
The game mashes up several Shakespeare plays, primarily Hamlet, but also Othello, Macbeth, Richard III, the Henry IV/Falstaff plays, Romeo and Juliet, and so on
Overall, this is one of the best theatre-based games available, and one of the best old-school games.
