MadTide

Dive the reef, ride the tide, and climb to the stars. A handcrafted underwater adventure — free, with no ads and nothing to buy. New daily challenge every day.

The tide is rising, the specimens are loose, and the reef is calling.

MadTide is a handcrafted underwater platform adventure: swim free, dash through danger, and follow the Crimson Reefbloom from a flooded research lab, across ten dives of open reef, to nine passages among the stars.

COMPLETELY FREE No ads. No purchases. No account. Your pearls are earned, never bought.
