Avenger [Abacus]

In the sequel to The Way of the Tiger, Yaemon the Grand Master of Flame is the villain of the piece. He has killed your foster-father Naijish and stolen the Scrolls of Kettsuin. Your quest to recover the scroll and avenge your father's death is viewed from above and superficially resembles Gauntlet. You start outside the Quench Heart Keep, and must initially find enough keys in the grounds and connected buildings to penetrate it, and then kill each of the 3 guards.
