Capacitor — hold to charge, release on the beat 0 / 4
Spectrum
Beat Runner
A race through the Lattice: an endless neon corridor that builds itself around whatever
music you feed it. Hold to charge the capacitor, release just before the stroke — the missile
lands on the beat. Clear every monster the tempo throws at you.

The tempo, the beat grid, the monster waves, the road pulse and the runner's speed are all derived
from an offline analysis of your file. Each beat you hold adds one bolt, so a four-beat charge
takes out four monsters at once — the diamonds show exactly which ones are locked.
Everything lands on the stroke: hitting it within ±90 ms is perfect
(±190 ms still good). Nothing is dodged — whatever reaches you has to be shot down,
so keep the charge running.
