Buoyage Direction
A mobile swipe game about IALA lateral buoyage. A navigation mark drifts toward your bow and you swipe left or right to pass it on the correct side; correctness depends on the region (A or B), the mark type, and the direction of buoyage. The region switches between channels, which is the real navigator's trap. Twelve channels end in a shareable passage chart.
