Pebble

Pebble is a calm, beautifully crafted stacking game about patience and timing.
A weightless pebble drifts back and forth above a quiet cove. Tap at the right
moment to let it fall, and watch it settle onto the tower you are building one
stone at a time. Land the pebble perfectly centered and the next stone keeps
its full width, your combo grows, and pearls drop into your pouch. Miss the
center too far and the stack narrows, the wind teases the next pebble, and the silence holds its breath.
