Labyrinth (1987)

A game of maze navigation, in which you race against time through random-generated labyrinths of varying difficulty levels. Not only does the complexity of the mazes vary, but another level of challenge is added through changes in the size of your viewport - more difficult levels zoom it inwards, making for a progressively shrinking section seen at a time.Quick navigation rewards you with accrued time bonuses for the next level; pebbles scattered through the labyrinth afford you points, as well as the option to drop them as landmarks - or to trade them in for a peek at the map.
