1Tap to charge
Every tap on Probe feeds the ring around it. A steady rhythm fills it faster than mashing, and near the end the screen shakes and the dark creeps in.

2Beat the anomaly
A full ring turns the screen dark and one short challenge surfaces. Clear it and your signal surges. Miss it and a heart goes.

3Climb the ranks
Three hearts, one run, one score. Your best run sets your rank, and every rank opens harder challenges.
Only a cleared anomaly scores. Clear them back to back and a streak multiplies each one, up to three times; miss one and it resets. The deeper a run goes, the harder every challenge gets. The first time you meet a challenge it is a practice round that costs no hearts.
The anomalies
Ten are open from your first run. Eleven more open as your best run climbs the ranks.
