In a tower with ever-climbing height, players subject multi-colored birds to a staccato drum of descending obstacles to prevent on-screen crashes.
The birds' flight is controlled solely by a tap-spacebar held in rhythm with the beat, yielding fleeting glimpses of green clearings and winking, helpful tips. The primary goal is to continually keep the birds aloft, coaxing up the tower through the coordination of timely taps. This game runs in a browser without the need for download or registration.
