Shell Guard

Turn a pearl shell to protect a tiny crab.

A bright three-wave arcade defense on a coral shoal. Turn the shell directly with the lower wheel and absorb incoming sea urchins. Each wave gives you three hearts; missed urchins in the same batch cost one heart together. Retry a fixed wave or protect the crab through all three.
