About Castle Nightingale, from BoardGameGeek:
Castle Nightingale looms out of the night, both intimidating and full of promise. Three ninjas have slipped inside, searching for the fabled treasure hidden within...yet a vigilant samurai patrols the halls, watching and listening for intruders.
Two players face off in Castle Nightingale, with the ninja player trying to steal five relics before the samurai player can capture the three ninja thieves. The castle is comprised of an inaccessible garden surrounded by four double-sided floor boards, each showing two secret passage spaces and areas in five colors.
Each turn, the ninja and samurai each choose one of three action cards in hand, with the samurai also choosing a nightingale tile not used on the previous turn. The ninja player resolves their action, then moves across the floor, marking each space of their movement with a footstep token. If they step on a colored space matching the samurai's hidden nightingale tile, the ninja stands revealed; otherwise, next turn the ninja can treat any of their footsteps as their starting space.
If the ninja picks up a vase, the samurai can still recover it on their turn by either closing the final secret passage or landing on the ninja's space...as long as the ninja has been revealed that turn. While the ninja moves space to space, the samurai treats each colored area as a single space, allowing them to move quickly within the castle.
Each player has specialized one-shot equipment they can use at any time, starting with one item and gaining more as they play certain cards. Each player has ten cards that they'll cycle through until either the samurai has captured all three ninja or the ninja have stolen five of the six relics hidden in the eight vases.
