The map

Every location, placed by the compass direction of the exits between them -- north up, east right, and up and down on the diagonals -- and moved aside where the game's geography will not fit a grid. A line is a way between two places, with a head at each end it can be taken towards; dashed, it goes through something, a door or a river. Click a place for its entry.

The markers along the top of a place are layers, each read from the game: the places that score the first time you reach them (VISIT_SCORES), the dark ones (bit 7 of a room record's first byte clear; see TOO_DARK), the places where arriving runs code of its own (ARRIVAL_HOOKS), the ends of the roads one of which is shut at the start of each game (HIDDEN_ROADS), and where each object and character starts, with how many. Tick a box to show a layer; hold the pointer over a marker for what it means.
