Steer a jazz-powered machine through the midnight rails while its weapon fires automatically. Dodge incoming projectiles, clear waves of noise-born enemies, and face a powerful boss every third wave as the tempo steadily rises.
Choose timed upgrades during each run to improve damage, fire rate, movement, pickup range, projectile speed, or Finale charge. Fill the Finale meter and unleash a sweeping special attack that clears hostile bullets and strikes every enemy on screen.
Ride the midnight rails, auto-fire, upgrade, and defeat rhythmic bosses.
