Clefbay ER

Clefbay is a complete offline instrument game. Finish onboarding, follow Walk through four moves, run Four Columns, choose a Range for the bay clock, and save a Tablet note. Home opens the fit bench, the world map, the shelf, the shop, the instrument card, and a phone-only hall board. Tap Bell, Valve, Slide, and Mouth to build the horn. There is no account, no login, no cloud sync, and no remote AI. Stars, hints, and notes stay on the device.
