Shake to play
The cicada orbits its stick and flutters its wings as you shake — shake harder and it spins and chirps faster.

Childhood, revisited
The toy you tied to a string as a kid.
Bamboo cicadas were a familiar summer toy across China — spin the tube on its string and it buzzes like a real cicada. 竹知了 brings that same simple pleasure to your pocket, with a couple of modern touches like custom sounds and a leaderboard.
