SporeSailBreeze

Portrait endless spore-sail gliding. The sail only travels the way it is pointed and the wind keeps turning, so running downwind is fast and pointing upwind crawls - the route is really shaped by the wind. Pollen drifting in the air is picked up on contact and scores, and each mote drifts back out somewhere else shortly after. White wind blades sweep across the field and shear a panel off the sail wherever they catch it, and a smaller sail both catches less wind and moves more slowly, so it gets harder to hold. The run ends once the sail has been cut away. A spore patch puts a large panel back, and a breeze shield blocks one blade for you. Endless mode with no fixed stage.
