First release. Ninety reef depths, four in-dive charms, the Tide Forge upgrade lines, a daily tribute and ten valor badges. Fully offline - no ads, no accounts, no in-app purchases. Colour-blind shape tags, reduced motion and larger digits are available from Tuning.
Only the current version so far — new entries appear as the game ships updates.
Drag ascending number bubbles into ladders and pop them before the tide wins.
