Moonminute · The Sandkeeper’s Bells
An original hourglass timing puzzle: turn reversible sand clocks, skip to the next emptying and ring exact ordered bells. Eight independently shortest-route-verified watches, partial-glass planning, exact nudges, unlimited undo, keyboard/touch, optional local chimes and device-only seals. GPT observatory and real chamber sand textures bundled locally. Idealized virtual clocks, not granular or gravity simulation. GitHub background reference only; no upstream code/models/assets reused.
