A fiendishly difficult jumping game in which you can only jump highest on the upbeats relative to a bass line. The closer you are to the upbeat, the higher your jump.

Tap the screen on the upbeats to make the bird fly and avoid the obstacles. Tap closer (in time) to the bass line for a lower jump.

An upbeat is the opposite of a downbeat. Tap your foot to the music playing. Now clap opposite your foot tapping. You're clapping upbeats. Simple, right? Now you're ready to play.
