Roll a luminous prism through river bridges, amber glass and split-cube puzzles.
Carry one small light across 33 original river crossings. Roll a lavender glass prism into each moonwell standing tall.
Circles and diamonds change the bridges. Amber glass holds a lying prism but breaks under its upright weight. Split rings send two small lights to separate banks; choose one, find a meeting place, and rejoin.
An unsupported step falls into the river and restarts the crossing. Your journey saves automatically, and each board has a six-digit code for returning later. A peaceful instrumental theme accompanies a growing series of spatial puzzles.
Reach the moonwell with the full prism standing upright. Circles respond to any part; diamonds need upright weight. Lie across amber glass. Split rings make two selectable halves that rejoin when settled edge to edge. A fall retries the current crossing.
