Echo Chamber
An echo expands from the centre. Click, tap, or press Space the instant it
crosses the green band. Nail it and the band tightens; miss it — or let the echo escape —
and you lose one of three lives.
Tip: catch on the band's leading edge — don't wait until you see it cross. A perfect centre hit builds a combo, up to ×5. It speeds up as you go, through the stages (Whisper → Resonance → Harmonic → Overtone…) — and each stage unlocks trickier target cadences, so no two runs play the same. Feats earn badges that stick across runs. And the deeper, cleaner players find the chamber has more to give.
