About Sonavault: Echo Descent

Sonavault is a short-session sonar puzzle game. Your survey craft starts in a dark field with seven hidden beacons. Tap to send a sonar pulse and the beacons in range glow for a moment before they fade back into the dark.

HOW IT PLAYS
- Tap anywhere in the field to pulse. The ring briefly lights up nearby beacons and nudges your craft toward the spot you tapped.
- Drag to steer the craft directly. Pass over a beacon to collect it.
- Each trial gives you a pulse budget. Tapping with no pulses left costs one of your three lives.
- Back-to-back collections build a chain multiplier, and pickups close to a beacon's center earn more stars.
- Collect the trial's beacon target to move on. The target starts at five and rises in later trials.

CAMPAIGN
- 60 trials. Each trial's beacon layout is generated from its own fixed seed, so a trial plays the same way whenever you return to it.
- The campaign map lets you jump to any trial and shows the stars and best score you have earned there.

DAILY AND LAB
- Daily: each date selects one campaign trial for everyone, worked out on your device without an account or server.
- Echo Mapper: a small practice panel with two sliders and an obstruction switch that shows how echo coverage and pulse reserve change a route-confidence score.

ALSO INCLUDED
- Five on-device achievements and a player records page.
- Haptic feedback switch.
- Works offline on iPhone and iPad. Progress stays on your device.
- No ads, subscriptions, in-app purchases, accounts, analytics or tracking.

Sonavault is an abstract puzzle game, not a navigation tool.
