Portrait endless quicksand climb. The sand ledges are laid up the face of the dune but they are running sand and keep slipping downward; tapping the ledge under your feet drives an anchor into it so it holds for a while, and tapping open air leaps you across. Anchors are limited and only come back over time, so the trick is to keep climbing while pinning the ledge you actually need. If the sand slips out from under you, or you leap and miss into the sand, the run ends there and then. The higher the score, the faster the sand runs. A solid anchor pins every ledge within a wide reach at once and holds them far longer, and a sky pad raises a temporary ledge you can stand on. Endless mode with no fixed stage.
